A food chain shows that plants are eaten by herbivores like rabbits, which are then eaten by carnivores like lions. Producers like plants make their own food and are the first link in the food chain, while consumers eat other organisms. Herbivores eat plants, carnivores eat meat, predators eat other animals, and prey are eaten by predators. Decomposers break down dead organisms. Humans, eagles and lions are at the top of food pyramids as they are rarely preyed upon by other animals.

Habitats and foodchains
An ecosystem refers to all the animals and plants that live together in one place and interact with each other. Different ecosystems can exist close together and some animals belong to multiple ecosystems. Every aspect of an animal's environment, including where it lives and the other organisms it interacts with, affects it. Animals are adapted to their environments through traits that help them survive, such as streamlined bodies that aid fish in swimming or thick layers of fat that insulate seals. A habitat is the place where an animal lives and finds what it needs to survive, like food, water and shelter. All living things require food and organisms in an ecosystem depend on each other for nourishment, with some animals eating plants or other animals. Food chains illustrate pred

What do animals eat
Animals are classified based on their diets as herbivores, which eat only plants; omnivores, which eat both plants and animals; and carnivores, which eat only meat. Herbivores are plant-eating animals, omnivores eat plants and other animals, and carnivores or meat-eaters survive solely on consuming other animals.
Food chain
The human digestive system is a complex series of organs and glands that processes food. In order to use the food we eat, our body has to break the food down into smaller molecules that it can process; it also has to excrete waste.Most of the digestive organs (like the stomach and intestines) are tube-like and contain the food as it makes its way through the body. The digestive system is essentially a long, twisting tube that runs from the mouth to the anus, plus a few other organs (like the liver and pancreas) that produce or store digestive chemicals.
Herbivore, carnivore and omnivore animals
There are three main types of animals: herbivores, carnivores, and omnivores. Herbivores get their energy from plants and grass. Carnivores get energy solely from eating other animals. Omnivores obtain energy from both plants and animals. All three types play important roles in ecosystems, and imbalances could disrupt entire food chains. Protecting ecosystems and reducing pollution will help ensure a healthy environment for all species.

This document discusses different types of animals and what they eat. It explains that cows, zebras and rabbits are herbivores that eat plants. Lions, tigers and crocodiles are carnivores that eat other animals. Bears, pigs, monkeys and people are omnivores that eat both plants and other animals.
Carnivore omnivore herbivore
An herbivore is an animal that eats only plants, though herbivores come in a variety of sizes and not just small. A carnivore is an animal that eats only meat and often have sharp teeth or fangs to help tear flesh. An omnivore is an animal that can eat both plants and meat, with people being omnivores that have flat and sharp teeth to digest a variety of foods including meat, fruit, and vegetables.
Carnivores, herbivores and omnivores
Carnivores eat only animals, herbivores eat only plants, and omnivores eat both animals and plants.
Food Chain Vocabulary: What’s for dinner?
The document defines key terms in a food chain including producer, consumer, decomposer, herbivore, carnivore, omnivore, predator, and prey. Producers are living things that make their own food, consumers eat other living things, and decomposers eat dead plants or animals. Herbivores only eat plants, carnivores only eat meat, and omnivores eat both plants and meat. Predators naturally prey on other animals, while prey are animals that are hunted for food by other animals.
Food chains (science)
This document discusses the different types of food chains that exist in nature. It explains that a food chain shows the order in which animals eat plants or other animals. Herbivores only eat plants, carnivores eat meat including animals that eat plants, and omnivores eat both plants and animals. Many food chains begin with insects eating plants, which are then eaten by fish, frogs, and birds, and the chain continues with birds and animals eating the fish. One example food chain shown is plants, insects, fish, frog, bear, and people.

Classifying animals according to the food they eat
This lesson plan classifies animals into three categories based on their diets: herbivores that eat plants, carnivores that eat other animals, and omnivores that eat both plants and other animals. It asks students to identify examples of bears, cows, goats, tigers, lions, and humans as belonging to these categories, and to consider whether herbivores can eat the same foods as carnivores and why or why not.
Ns3 unit 1 life processes in animals
The document discusses different aspects of animals including their nutrition, interaction with their environment, and reproduction. It notes that animals eat a variety of foods including plants, plants and animals, or other animals. It also describes how animals move in different ways like swimming, flying or running to find food or escape predators, and that they live together in groups or are born from eggs or live birth.
Carnivores
Kyle Young presents on various carnivorous animals and plants. Some key points:
- Carnivores derive energy and nutrients from consuming the flesh of other animals through predation or scavenging. They play an important role in ecosystems.
- Examples of carnivores include lions, tigers, bears, snakes, vultures, sharks, Tasmanian devils, and carnivorous plants like the Venus fly trap.
- These carnivores have evolved different physical adaptations and behaviors to hunt and consume prey effectively based on their environment, such as sharp teeth, claws, acute senses of smell, flexibility, and digestive enzymes.
- Humans also have relationships with some carnivores like domestic

This document provides information about different types of animals. It begins by distinguishing between domestic animals, such as cows and horses, that live on farms and homes, and wild animals that live in jungles. It then describes how various animals help humans by providing milk, eggs, meat, wool, and other products. The document also discusses the different eating habits of herbivores, carnivores, and omnivores. It provides examples of food chains in nature and emphasizes the importance of protecting endangered animal species.
FINAL presentation on "how do living things interact?"
This document discusses ecosystems and how living and non-living things interact within them. It defines key terms like producers, consumers, decomposers, food chains, and food webs. Producers (plants) produce their own food, consumers (animals) eat other organisms, and decomposers (fungi, bacteria) break down dead organisms, recycling nutrients. Food chains show energy transfer between organisms, while complex food webs connect multiple chains in an ecosystem. All organisms depend on each other for survival.

Hello im sirsak and im neeth ^ ^
The document discusses key concepts related to food chains and biomass. It defines biomass as the total mass of a living thing excluding water. Biomass is composed of glucose and other substances produced through photosynthesis. A food chain diagrams how organisms feed on each other in an ecosystem, with producers like plants generating their own food, and consumers like herbivores and carnivores eating other organisms or animals. Decomposers feed on dead plants and animals. An example food chain is given of grass being eaten by a grasshopper and further up the chain.
Three Kinds of Consumers
This document discusses the three main types of consumers: carnivores, herbivores, and omnivores. Carnivores only eat meat from other animals. Herbivores only consume plants. Omnivores have a mixed diet of both meat and plants. Examples are provided for each consumer type, including lions, cows, and humans (omnivores).
We Do_Hungry AlligatorRobotics[
1) The document describes an educational robotics project where students build a model of a hungry alligator using WeDo kits. The alligator model is programmed to open and close its jaw when it "eats".
2) Alligators typically eat fish, insects, snails, and other small animals when young, and progressively larger prey like turtles and mammals as they grow older. They should not be petted due to their predatory nature.
3) The project teaches students about alligator biology, behavior, habitat, and reproduction, and how electrical energy is transferred to make the mechanical alligator jaw move.

The document discusses the ozone layer, which absorbs much of the sun's harmful UV radiation and helps prevent damage to human skin. The ozone layer is located high in the atmosphere and consists of ozone molecules. Chemicals called CFCs can destroy ozone, reducing its ability to absorb UV radiation. The passage distinguishes the ozone layer from the topic of global warming and poses a question about factors that can alter the balance.
C2g,H Rates Of Reaction
This document discusses how changing temperature affects the rate of a chemical reaction. It explains that increasing the temperature speeds up the reaction for two reasons: 1) Higher temperatures cause particles to move faster, giving them more energy and increasing the collision rate. 2) Higher temperatures provide particles with more energy, allowing harder, more successful collisions that further increase the reaction rate.

P2h Big Bang
The document discusses the origins and evolution of the universe from the Big Bang to the present. It describes how the Big Bang resulted in a hot, dense cosmic soup of protons, neutrons and electrons that cooled over time and formed the first atoms of hydrogen and helium. Gravity caused these atoms to coalesce into the first stars and galaxies. Over billions of years, gravity continued to draw matter together, forming more complex structures like planets and solar systems. While much is understood about how the universe has evolved since the Big Bang, key questions remain about what triggered the initial expansion and what the ultimate fate of the universe may be.
C3c Covalent Bonding,Structure Periodic Table
Covalent bonding occurs when nonmetal atoms share electrons to form molecules. The dot and cross diagram model represents how electrons are shared in molecules like H2, Cl2, CH4, CO2, and H2O. Covalently bonded substances have properties like low melting and boiling points as the weak intermolecular forces allow the molecules to move apart easily. They also do not conduct electricity as there are no free electrons to move. The periodic table arranges elements in periods and groups based on their atomic structure. The group number represents the number of electrons in the outer shell, which determines an element's chemical properties.

Introduction to Food Chains
A food chain shows how energy flows through an ecosystem. All food chains begin with the Sun providing energy to green plants, which are producers. Producers are then eaten by primary consumers like insects and herbivores. Secondary consumers eat primary consumers, and tertiary consumers eat other consumers. Food chains illustrate the relationships between organisms as energy passes from one to the next.
FOOD CHAINS UNIT 3 YEAR 3
Food chains show how organisms within an ecosystem rely on each other for energy and nutrients. Plants are producers as they produce their own food through photosynthesis. Herbivores consume plants and carnivores consume herbivores or other carnivores. Lions are an example of an apex predator, occupying the top of some terrestrial food chains, as no other animals prey on them. Disruptions anywhere in a food chain can impact the entire ecosystem.
Habitats And Foodchains[1]
An ecosystem refers to all the animals and plants that live together in one place and interact with each other. Different ecosystems can exist close together and some animals belong to multiple ecosystems. Every aspect of an animal's environment, including where it lives and the other organisms it interacts with, affects it. Animals are adapted to their environments through traits that help them survive, such as streamlined bodies that aid fish in swimming or thick layers of fat that insulate seals. A habitat is the place where an animal lives and finds what it needs to survive, like food, water and shelter. All living things require food and organisms in an ecosystem depend on each other for nourishment, with some animals eating plants or other animals. Food chains illustrate pred
6yr 09 #12 Food Chains
This document discusses food chains and ecosystems. It defines a food chain as showing what eats what in an ecosystem. An ecosystem includes all the animals, plants, and their habitats that provide everything needed to sustain life. This particular food chain shows plants being eaten by slugs, slugs eaten by frogs, and frogs eaten by herons. Most food chains begin with a green plant that acts as a producer, making its own food. Animals that eat plants or other animals are consumers. Predators are animals that hunt and eat other animals, while prey are animals that are hunted and eaten. Energy flows through the food chain as each organism eats another to gain energy, keeping the ecosystem alive.

Ecosystems & food chains
This document discusses ecosystems, habitats, food chains, and the relationships between different organisms within an environment. It provides examples of how different animals such as seals, squirrels, and fish are adapted to their environments. It also explains producers and consumers within food chains, with plants being producers, herbivores being primary consumers, carnivores being secondary consumers, and omnivores consuming both plants and animals. Predator-prey relationships and complex food webs are described. Threats to habitats and organisms becoming endangered or extinct are also covered.
Feeding
The document discusses feeding relationships and food chains. It explains that all food chains start with energy from the sun which is transferred to plants through photosynthesis. Plants are called producers. Primary consumers, like rabbits and aphids, eat the plants and pass the energy to secondary consumers like foxes and ladybirds that prey on the primary consumers. A food web shows the complex interconnected feeding relationships between different species in an ecosystem. When a species is removed, it impacts the populations of the other connected species in the food web.
Biogeography- food chain and foo web
This document discusses food chains and food webs. It begins by defining a food chain as a sequence of organisms where each uses the next lower member as a food source. Food chains were first introduced in the 9th century and later popularized in a 1927 book. A food chain shows how energy passes from producers like plants through herbivores and then carnivores. Many interconnected food chains make up a food web. A food web representation shows all possible feeding relationships in an ecosystem. Whether a food chain or food web, the survival of plants and animals depends on their interdependence with each other.
Food chain group 3-9 f
A food chain shows how organisms obtain energy and nutrients by consuming other organisms. Food chains begin with autotrophs, like plants, that produce their own food. Herbivores then eat the plants, and carnivores eat the herbivores or other carnivores. This continues with increasing trophic levels until reaching top predators with no natural predators. At each level some energy is lost, with decreasing amounts of energy being passed to higher levels.
Animal Behavior: Food selection sudeshrathod
Food selection depends on the energy strategy of the feeder. The food size, quantity and quality varies with species to species and also depends on the ability of feeder, its body size etc.
Feeders are either specialists or opportunists. Food selection depends on competitive principle, learned aversion and food energy budget.
Ecology
Ecology is the scientific study of interactions between organisms and their environments, focusing on energy transfer. There are three main types of feeding relationships: producer-consumer, predator-prey, and parasite-host. Producers, like plants, make their own food through photosynthesis. Consumers eat other organisms for energy and include both predators that hunt prey and animals that eat plants or other animals. A food chain shows what organisms eat in a linear feeding order starting with producers, while a food web depicts the complex and interconnected feeding relationships in an ecosystem.
The Food Web PowerPoint
This presentation is a PowerPoint on the Food Web I completed in Geology. This goes into great detail about consumers, producers, and decomposers.
Consumer
This document defines and categorizes consumers into three types: primary, secondary, and tertiary consumers. Primary consumers, such as herbivores, eat producers like plants. Secondary consumers are carnivores that prey on primary consumers, such as foxes eating squirrels. Tertiary consumers occupy the top of the food chain and eat other animals, including secondary and some primary consumers, like hawks preying on foxes.
Food chains
A food chain describes how energy and matter move between organisms in an ecosystem. It typically consists of producers, primary consumers, secondary consumers, tertiary consumers, and decomposers. Producers, such as plants and algae, use photosynthesis to convert sunlight into food. Primary consumers eat producers. Secondary consumers eat primary consumers, and tertiary consumers eat secondary consumers or other tertiary consumers. Decomposers, like fungi and bacteria, break down the remains of dead organisms and return nutrients to the soil or water.
3rd Grade Science Unit
The document provides information about a science unit on living things and how they interact. It includes 5 lessons on animals, producers and consumers, carnivores, herbivores and omnivores, and food chains and webs. Lesson 3 focuses on classifying animals as carnivores, herbivores or omnivores based on what they eat. Activities include a Venn diagram and arranging animals into the three groups. Key words are also defined.
Energy flow
The document discusses how energy flows through ecosystems. It begins by explaining that all organisms require energy, which they obtain by consuming other organisms or producers like plants. It then provides an example food chain of grass, a zebra that eats the grass, a lion that eats the zebra, and scavengers that eat the lion. The document goes on to define trophic levels and explains that the sun is the primary energy source for ecosystems. It describes producers, primary consumers, secondary consumers, scavengers and decomposers. Finally, it notes that the energy available at each trophic level decreases by around 90% at each transfer of energy.
Queency powerpoint
1) Food chains describe the transfer of energy from producers to consumers in an ecosystem. Producers such as plants get energy from the sun which is then consumed by primary, secondary, and tertiary consumers.
2) Organisms obtain food through predation, symbiosis, and mutualism. In predation, one organism hunts another for food. Symbiosis describes living together, including parasitism where one benefits at the expense of the other, commensalism where one benefits without affecting the other, and mutualism where both benefit.
3) Disruptions to the food chain, such as the loss of a population like frogs in a pond, can negatively impact other populations that depend on
Food chain
This document provides information about food chains. It begins by defining a food chain as a sequence of organisms through which energy flows as each organism obtains energy from the one below it in the chain. Producers, such as plants, are at the bottom of the food chain as they can produce their own food. Herbivores, as primary consumers, eat the producers. Carnivores eat herbivores or other carnivores. Omnivores both eat plants and other animals. Decomposers, like fungi and bacteria, break down waste and dead organisms, recycling nutrients in the ecosystem. The document includes examples of food chains and defines the roles of producers, consumers, and decomposers. It also
Food Chains and Webs
The document discusses the roles of organisms in ecosystems, including producers, consumers, and decomposers. Producers such as plants make their own food through photosynthesis. Consumers obtain food by eating other organisms and can be primary, secondary, or tertiary consumers depending on what they consume. Decomposers like bacteria and fungi break down dead organic material and return nutrients to the soil. The document also defines food chains as simple representations of feeding relationships and food webs as more complex networks of interconnected food chains within an ecosystem.
Nehaa Presentation Science 1.pptx

Photography derives from the Greek words for "light" and "to write" and the word was coined by Sir John Herschel in 1839. Early philosophers and mathematicians described the principles of the pinhole camera as early as the 5th century BC, though the first photographs were not made until combining several technical discoveries. Cameras are now widely used around the world to capture wonderful sights and are symbols of both paparazzi and human freedom and ingenuity.
Space
The document discusses several topics related to astronomy and space, including:
- The formation of elements like hydrogen in the Big Bang and later fusion in stars that led to heavier elements like carbon.
- How satellites orbit Earth due to centripetal force balancing gravitational attraction, with examples of low polar orbits and geostationary orbits.
- How planets orbit the Sun due to centripetal force balancing gravitational attraction.
- How the Sun will evolve over time from its current stable phase into a red giant and later a white dwarf or neutron star/black hole.
Radiation
In alpha decay, the nucleus loses 2 protons and 2 neutrons, decreasing the atomic number by 2 and mass number by 4. In beta decay, a neutron changes to a proton and an electron is ejected, increasing the atomic number by 1 while keeping the mass number the same. In gamma decay, only energy is emitted with no change to the atomic or mass number.
Motion
Forces add up as vectors, so a 10N force to the left and an 8N force to the right result in a 2N force to the left. If the net force is zero, the object will stay at rest or move at a constant velocity. If there is a net force, the object will accelerate according to F=ma. Projectiles follow parabolic paths and take the same time to fall as dropped objects. Kinetic energy equals half the mass times the velocity squared.
Light
The document summarizes key aspects of different parts of the electromagnetic spectrum including radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. It also discusses properties that apply across the spectrum such as all waves traveling at the speed of light, interference and diffraction effects. Additionally, it covers topics in waves and optics including reflection, refraction, lenses, sound waves, and seismic waves.
Energy
Heat is transferred through particles vibrating (conduction), air rising when hot (convection), and radiation being absorbed and reflected. Insulation in walls traps air which is an insulator, while different methods like passive solar heating and fossil fuels generate heat energy through various processes. When a solid melts it changes state at a constant temperature.
Electomagnets
1) When a current passes through a copper wire in a magnetic field, it induces a voltage in the wire due to electromagnetic induction.
2) An alternating current generator uses a rotating coil in a magnetic field to generate a current, where the direction of the current reverses as the coil rotates.
3) Transformers use the principle of electromagnetic induction to change the voltage of an alternating current - a step-up transformer increases voltage through more turns on the secondary coil, while a step-down transformer decreases voltage.
Electronics
1) Electrostatic charges involve the attraction and repulsion of objects based on whether they have equal or opposite charges. Charges are used in photocopiers, dust precipitators, and defibrillators.
2) Electricity involves the flow of electrons through conductors. The resistance of materials can change based on factors like temperature. Common circuit components include resistors, diodes, and capacitors.
3) Digital and analog signals are used to transmit information. Digital signals use 1s and 0s while analog signals have continuously varying values. Multiplexing and sampling allow more data to be transmitted.

The document defines key terms related to food chains and food webs, including biomass, producer, consumer, herbivore, carnivore, predator, prey, decomposer. It provides an example food chain starting with plants as producers, then herbivores, primary and secondary consumers, and ending with a carnivore or tertiary consumer at the top. A diagram shows how energy transfers through a pyramid-shaped food web from producers to different consumer levels.
Food chains
A food chain shows how each living thing gets its food, with arrows indicating what eats what. Carnivores are meat-eating animals like cats, lions, and snakes. Producers like plants make their own food through photosynthesis. Consumers eat other organisms, and can be herbivores that eat plants or predators that hunt other animals. Prey are the animals or plants that are hunted by predators.
Food chains project
The document defines key terms related to food chains and ecosystems:
1) Biomass refers to dead plant and animal material that can be used as fuel.
2) A food chain describes a series of living things connected by predation, with each organism eating the one below it.
3) Producers are plants that use sunlight to produce their own food.
4) Consumers are herbivores, zooplankton and carnivores that eat other organisms.
5) Herbivores eat only plants, carnivores eat meat, and predators hunt other animals for food.
Food chain with alice
The document describes various food chains that exist on Earth and a hypothetical food chain on Mars. On Earth, producers like plants undergo photosynthesis at the bottom of the food chain, while consumers like herbivores and carnivores eat other organisms or animals higher up the chain. A food chain in the ocean includes phytoplankton, zooplankton, fish, and blue whales. The hypothetical Martian food chain positions Mares bacteria at the bottom, which are eaten by Mares aliens that feed on rocks. These aliens are preyed upon by the apex predator Sky beasts.
Sunni and nish foód¦¬presentaion
Biomass refers to the total mass of living organisms in an ecosystem, excluding water. Producers in a food chain are always plants, which produce their own food through photosynthesis. A food chain represents the predator-prey relationships between species in an ecosystem, with producers like plants being eaten by consumers such as snails, fish and ducks, and with carnivores preying on other animals and serving as predators for their prey.

Unit 2 9 Mechanisms Notes
This document provides an overview of organic reaction mechanisms. It begins by explaining that chemical reactions can be studied in detail by examining how electrons move during the reaction, known as the reaction mechanism. It then discusses different types of organic reactions like addition, elimination, and substitution. The document also categorizes reagents as nucleophiles or electrophiles. It explains how single bonds can break through homolytic or heterolytic fission. Finally, it discusses free radical chemistry and how CFCs catalyze the destruction of stratospheric ozone through a free radical chain reaction.
Solar Elyse And Jeong
The document discusses solar energy, including what it is, how it is harnessed, where it comes from, its advantages and disadvantages, and some of its uses. Solar energy comes from the sun and can be used to generate electricity or heat water. It is harnessed using solar panels that convert sunlight into electrical energy or use it to heat fluids. While a renewable source of energy, solar power has initial costs and requires large land areas for panels, and production of panels can release toxic byproducts if not properly handled.
Future Transport Nishan And Sunny
Alternative fuels are fuels other than conventional fossil fuels like oil, coal, and natural gas. Some common alternative fuels include biodiesel, ethanol, hydrogen, and electricity from batteries, fuel cells, solar, or wind power. Alternative fuels are needed because fossil fuel resources are running out and renewable alternatives are needed. Battery electric vehicles use electric motors powered by rechargeable battery packs instead of gasoline engines. They have less pollution than gas cars but slower charging times and speeds. Solar cars are powered by solar panels that convert sunlight directly into electrical energy for electric motors. They produce zero emissions but are expensive and can only be used during the day. Fuel cells produce electricity through chemical reactions without combustion, which can be used to power electric
Nuclear And Geothermal Neeth And Sirsak
Nuclear energy generates electricity by splitting or fusing atomic nuclei, releasing energy according to Einstein's mass-energy equivalence formula. Geothermal energy taps heat from the earth's core to generate electricity. Both use heat to generate electricity, with nuclear providing low-cost, low-pollution power. France generates over 75% of its electricity from nuclear energy due to energy security policies. Geothermal energy is also used for district heating and bathing.
Wind Alice, Amit And Amy
Wind energy is a renewable source of energy that is harnessed using wind turbines located in wind farms. Wind turbines convert the kinetic energy of wind into electrical energy, with the turbine blades spun by wind currents that are ultimately driven by the sun. Wind power is being used increasingly all over the world, with wind farms established in locations like the UK and Australia to generate electricity from wind energy.
Biomass Harishan And Benji
Biomass is biological material from living or recently living organisms that can be used as an energy source. Examples of biomass include wood, trees, shrubs, crops, grasses, algae, and animal and food waste. Biomass is a renewable source of energy because it comes from sunlight that plants absorb to grow, and biomass can be regrown as it is used. Biomass is burned in boilers to produce steam that turns turbines and generates electricity.
