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.

Producers
Organisms get energy from their ecosystem, with some making their own food through photosynthesis like producers such as plants, grasses, shrubs, trees and algae. Producers use energy from sunlight to produce their own food through photosynthesis, providing oxygen and food for other organisms. Some organisms take in food as consumers while others break down wastes as decomposers.
Energy flow
1) Energy from the sun powers photosynthesis in producers, enabling the storage of chemical energy in molecules. 2) This energy then flows through ecosystems as organisms feed on each other across trophic levels. 3) As energy moves up food chains, about 90% is lost as heat at each level, so insects gain only 10% of the energy trapped by plants, and so on.

The document describes the food chain and how energy from the sun is transferred through producers, consumers, and decomposers. It provides definitions of key terms and explains how photosynthesis allows plants to convert sunlight into food energy. Students are instructed to create two food chains using provided cutouts and explain how each step transfers energy. An extension activity challenges students to make their own long food chain and consider how extinction would affect the chain.
Food and energy in the environment
This document discusses how organisms obtain energy and their roles in ecosystems. Producers, like plants, generate their own food through photosynthesis. Consumers, such as herbivores, carnivores and omnivores, obtain energy by eating producers or other consumers. Decomposers, including bacteria and fungi, break down dead organisms and cycle nutrients back into the environment. Food chains and webs represent the transfer of energy as organisms consume other organisms. Producers are the first level, while consumers and decomposers occupy higher levels, with less available energy at each step.

1) Energy from the sun is absorbed by producers like plants through photosynthesis and converted into chemical energy in sugars. 2) Consumers obtain this energy by eating producers or other consumers. 3) Decomposers break down dead organisms, releasing nutrients back into the environment and completing the energy cycle.
Introduction to energy flow
The document introduces the concepts of energy flow through food chains and webs in ecosystems. It explains that the sun is the ultimate energy source and that plants convert the sun's energy to food through photosynthesis. This energy then flows to consumers as herbivores eat plants and carnivores eat herbivores or other carnivores. Detritivores and decomposers break down dead organic matter, recycling nutrients and energy back into the system. Food chains illustrate a single path of energy transfer, while food webs show the multiple feeding relationships in an ecosystem.

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 by Ammar Raed
Food chains describe how energy passes from one living thing to another as each organism obtains energy by consuming other organisms or plants. Plants get energy directly from the sun while other organisms get energy by eating plants or other organisms. Examples of food chains include a desert food chain with the sun providing energy to sagebrush which is eaten by grasshoppers and then lizards and hawks, and a marine food chain with plankton, mussels, fish and bigger fish. Food chains can be simple with just a few organisms or more complex involving multiple organisms transferring energy up the chain from nuts to mice to snakes and hawks and eventually to humans.
Energy flow in ecosystems
1) Energy from the sun is captured by producers like plants through photosynthesis and converted into chemical energy stored in organic molecules. 2) Primary consumers, like herbivores, obtain this energy by consuming producers. Secondary consumers eat primary consumers. 3) Energy is lost at each trophic level, with only about 10% transferred between levels. This limits the length of food chains and the number of organisms an ecosystem can support.
Food chains and food webs
The document discusses trophic levels and food chains in ecosystems. It explains that the sun's energy is captured by producers through photosynthesis and then transferred to consumers through eating. This creates trophic levels with producers at level 1, primary consumers at level 2, secondary consumers at level 3, and so on. Food chains show direct energy transfers between organisms but ecosystems actually contain complex food webs. Energy is lost at each transfer through inefficiencies in transformations between chemical and kinetic energy.
Lecture 2 energy & relationships
This document discusses key ecological concepts including trophic levels, energy flow through ecosystems, and nutrient cycling. It defines producers as autotrophs that obtain energy from sunlight or chemicals, and consumers as heterotrophs that obtain energy by eating other organisms. The five main trophic levels are described as primary producers, primary consumers, secondary consumers, tertiary consumers, and detritivores/saprotrophs. Photosynthesis, food chains, and energy and matter cycling are also summarized.

Ecosystem energy flow (part 1)
The document discusses energy flow through ecosystems. It defines producers as organisms that can produce their own food through photosynthesis, such as plants and algae. Consumers are organisms that cannot produce their own food and obtain energy by eating other organisms. There are three types of consumers: primary consumers that eat producers, secondary consumers that eat primary consumers, and tertiary consumers that eat secondary consumers. Decomposers, such as fungi and bacteria, obtain energy by breaking down dead organisms and recycling nutrients.
Ecosystems and Energy
Producers like plants, algae and some bacteria capture energy from sunlight through photosynthesis. Consumers obtain energy by eating other organisms and include herbivores, carnivores, omnivores and scavengers. Decomposers break down dead organisms and return nutrients to the soil, functioning like nature's recyclers. Food chains show the transfer of energy between organisms, always beginning with a producer and ending with a consumer. Climate change can affect ecosystems by altering environmental conditions.
Energy flow
In ecology, energy flow, also called the calorific flow, refers to the flow of energy through a food chain. In an ecosystem, ecologists seek to quantify the relative importance of different component species and feeding relationships.
A general energy flow scenario follows:
Solar energy is fixed by the photoautotrophs, called primary producers, like green plants. Primary consumers absorb most of the stored energy in the plant through digestion, and transform it into the form of energy they need, such as adenosine triphosphate (ATP), through respiration. A part of the energy received by primary consumers, herbivores, is converted to body heat (an effect of respiration), which is radiated away and lost from the system. The loss of energy through body heat is far greater in warm-blooded animals, which must eat much more frequently than those that are cold-blooded. Energy loss also occurs in the expulsion of undigested food (egesta) by excretion or regurgitation.
Secondary consumers, carnivores, then consume the primary consumers, although omnivores also consume primary producers. Energy that had been used by the primary consumers for growth and storage is thus absorbed into the secondary consumers through the process of digestion. As with primary consumers, secondary consumers convert this energy into a more suitable form (ATP) during respiration. Again, some energy is lost from the system, since energy which the primary consumers had used for respiration and regulation of body temperature cannot be utilised by the secondary consumers.
Tertiary consumers, which may or may not be apex predators, then consume the secondary consumers, with some energy passed on and some lost, as with the lower levels of the food chain.
A final link in the food chain are decomposers which break down the organic matter of the tertiary consumers (or whichever consumer is at the top of the chain) and release nutrients into the soil. They also break down plants, herbivores and carnivores that were not eaten by organisms higher on the food chain, as well as the undigested food that is excreted by herbivores and carnivores. Saprotrophic bacteria and fungi are decomposers, and play a pivotal role in the nitrogen and carbon cycles.
The energy is passed on from trophic level to trophic level and each time about 90% of the energy is lost, with some being lost as heat into the environment (an effect of respiration) and some being lost as incompletely digested food (egesta). Therefore, primary consumers get about 10% of the energy produced by autotrophs, while secondary consumers get 1% and tertiary consumers get 0.1%. This means the top consumer of a food chain receives the least energy, as a lot of the food chain's energy has been lost between trophic levels. This loss of energy at each level limits typical food chains to only four to six links.

Tema 4 food chain
Living things can live in different ecosystems like forests, deserts, and seas, but all living things depend on other living things. A food chain shows the feeding relationships between organisms, with producers like plants forming the base and being eaten by primary consumers like grasshoppers and secondary consumers like frogs and herons. A food chain is completed by decomposers like bacteria and fungi that break down dead organisms.

The document discusses the key components and dynamics of an ecosystem. It can be summarized as follows:
1. Ecosystems are made up of interacting abiotic and biotic factors that exchange energy, nutrients, and minerals through food chains, webs, and biogeochemical cycles.
2. Energy enters from the sun and is converted to chemical energy by producers through photosynthesis, with about 10-20% transferred to secondary consumers.
3. Nutrients and minerals circulate through the ecosystem, being used and reused, while energy flows in one direction from producers to consumers at different trophic levels.
Ecology energy flow food chains
Ecology is the study of interactions between organisms and their environments. There are several levels of ecological organization, including the biosphere, ecosystems, populations, and communities. Energy flows through ecosystems from producers like plants and photosynthetic bacteria to consumers at different trophic levels in food chains and webs. Only about 10% of energy is transferred from each trophic level to the next higher level.
Biology ecology
The document discusses different levels of organization in ecology, from cells to the biosphere. It explains key ecological concepts like producers, consumers, herbivores, carnivores, omnivores, decomposers, food chains, food webs, and energy flow through ecosystems. Primary productivity is defined as the rate at which producers create new organic material. Major biogeochemical cycles like the water, carbon, and nitrogen cycles are also summarized.

This document summarizes key concepts in ecology, including defining abiotic and biotic factors, ecosystems, and levels of biological organization. It describes how biotic factors such as producers, consumers, and decomposers interact through food chains and webs within ecosystems and explains concepts like trophic levels, energy flow, and ecological relationships between species through competition, predation, and symbiosis.
Energy Flow In An Ecosystem
Here are the key points about how energy flows through ecosystems:
- Energy from the sun is captured by producers (plants) through photosynthesis and stored as chemical energy in glucose.
- Primary consumers (herbivores) obtain energy by eating producers. Secondary consumers (carnivores) obtain energy by eating primary consumers. Tertiary consumers obtain energy by eating secondary consumers.
- Most energy is lost at each transfer between trophic levels, so the amount of available energy decreases moving up the food chain.
- Scavengers and decomposers (bacteria, fungi) break down dead organisms, recycling nutrients back into the soil/environment where producers can use them again.
- Nutrient cycling
Energy Flow In Ecosystems
The document discusses energy flow through ecosystems and food webs. It provides several field notes describing relationships between different organisms, such as plants being eaten by herbivores or smaller organisms being eaten by larger predators. It then explains that as energy moves through food chains and webs, the vast majority (around 90%) is lost as heat, so there is only about 10% of the original energy available at each trophic level. This pattern can be represented through an energy pyramid diagram.
final document
1. Biotic components are the living things in an ecosystem, including producers, consumers, and decomposers.
2. Producers like plants use photosynthesis to obtain energy from sunlight. Consumers eat producers or other consumers to obtain energy, and can be herbivores, carnivores, or omnivores. Decomposers obtain energy from dead producers and consumers.
3. Food chains show the feeding relationships between organisms, with energy passing from producers to primary, secondary, and tertiary consumers.
Ecology energy flow pathway in an ecosystem
The document discusses energy flow through ecosystems. It begins by explaining that the sun is the primary energy source for ecosystems and that plants convert the sun's radiant energy into chemical energy through photosynthesis. This chemical energy then passes through food chains, with approximately 10% of the energy being transferred to each higher trophic level. Various models and laws are described that illustrate principles like the one-way flow of energy and the inefficiencies of transfers between trophic levels. Overall, the summary emphasizes that sunlight powers ecosystems by being converted to chemical energy by plants and then traveling through food webs in a step-wise, 10%-losing manner.
Feeding relationships
Organisms in an ecosystem are interconnected through feeding relationships. Producers, such as plants and algae, can create their own food through photosynthesis, obtaining energy from the sun and nutrients from their environment. Consumers, or heterotrophs, obtain food by eating other organisms and pass sunlight energy through the food chain. There are different levels of consumers, including primary, secondary, and tertiary. Decomposers help release nutrients by breaking down waste and dead organisms, recycling carbon, nitrogen, and phosphorus back into the ecosystem.
Pyramids of biomass, energy loss
This document discusses energy loss in food chains and the carbon cycle. It notes that as the number of stages in a food chain increase, more energy is lost at each transfer between trophic levels. Consumers use some of the energy they obtain from food for respiration and movement, and the rest is lost as waste, heat, or is stored in their body mass. Specific examples given are that a cow obtains 100kJ from food but only 4kJ is stored in its muscle tissue, while 33kJ is used for respiration and 63kJ is lost as waste, heat, or gas.
Pyramid Of Numbers And Biomass
Pyramids of number and biomass are visual representations of food chains. A pyramid of number shows the number of organisms at each trophic level, such as one hawk needing 100 blue tits. A pyramid of biomass shows the biomass or energy at each level, with less biomass at higher trophic levels due to energy being lost as it transfers between levels. The document provides examples of drawing pyramids of number and biomass for different food chains.

It defines a food chain as the transfer of energy from producers, like plants, through consumers at different trophic levels, and explains the key levels as producers, primary consumers, secondary consumers, and decomposers. Food webs are described as interconnected food chains that form a network of feeding relationships between species. Ecological pyramids illustrate the structure of ecosystems by depicting the numbers, biomass, or productivity at each trophic level, with producers at the base and top predators at the apex. Disturbances like bioaccumulation and biomagnification of chemicals can disrupt ecosystem balance.

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.

Here are 3 potential impacts if grasshoppers disappeared from the area:
1. The vole population would decrease. Without grasshoppers as a food source, voles would have less available food and their population would decline over time.
2. The frog and snake populations would decrease. With fewer voles due to the lack of grasshoppers, the frog and snake populations that rely on voles as a food source would have reduced availability of prey. Their numbers would fall as a result.
3. Other animals higher up in the food chain like hawks and owls would be indirectly impacted. With declining frog and snake populations due to fewer voles, these top predators would have reduced populations of smaller animals to prey
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.
Living things get energy
This document discusses energy flow and food chains in ecosystems. It explains that producers like plants get energy from sunlight to make food, while consumers eat other organisms or producers for energy. Decomposers break down dead organisms and waste, releasing energy back into the ecosystem. Food chains show how energy passes from producers to consumers. Multiple overlapping food chains combine to form complex food webs, where a change in one part can impact other parts of the ecosystem. The document gives an example of how reducing the habitat for prairie dogs due to human settlement can negatively affect other species in the food web like black-footed ferrets and badgers by decreasing their food sources.
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
Biosphere
Earth has four main interacting systems: the atmosphere, hydrosphere, biosphere, and geosphere. The biosphere contains all living things and is dependent on abiotic and biotic factors. Energy from the sun moves through food chains and webs as organisms consume other organisms or plants. Herbivores eat plants, carnivores eat herbivores or other carnivores, and omnivores eat both plants and animals. Decomposers break down waste and cycle nutrients through the biosphere.
Earth Science. Biosphere ppt
The document discusses the four main systems that make up Earth: the atmosphere, hydrosphere, biosphere, and geosphere. It focuses on explaining the biosphere and related concepts like ecology, biotic and abiotic factors, food chains, and food webs. The biosphere is made up of all living things that interact with each other and non-living things. Energy from the sun is passed between organisms through food, starting with producers and moving up through herbivores, carnivores, and decomposers. Food chains connect to form more complex food webs in ecosystems.
food chains and food webs
1) A food chain models the flow of energy from one living thing to the next as organisms consume each other. All food chains begin with producers, such as plants, that obtain energy from the sun.
2) If one organism in a food chain is removed, all other organisms in the chain are affected as the energy flow is disrupted.
3) Multiple interconnected food chains form a more complex food web. Like food chains, food webs also begin with energy from the sun and producers, and the removal of any organism can impact the entire web.
Food webs
This document discusses food chains and how they work. It explains that food chains show how plants, animals, and humans rely on each other for food. Animals get energy by eating other animals or plants, forming links in a food chain. If one part of the food chain is disrupted, like a disease wiping out a species, it can affect the entire chain. The document also defines producers as plants that make their own food, consumers as animals that eat other organisms, predators as animals that eat other animals or prey.
B) How It Works
1. Producers such as plants use photosynthesis to produce their own food from sunlight, acting as the base of the food chain. Consumers obtain food by eating other organisms and can be herbivores, carnivores, or omnivores.
2. Energy passes from producers to primary consumers like herbivores and then to secondary consumers such as carnivores in a food chain. Multiple interconnected food chains make up a complex food web in an ecosystem.
3. As energy passes up the food chain, much of it is lost at each transfer between organisms and is used for functions like movement, growth, and heat rather than being fully passed to the next organism. This limits how many organisms can
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. All living things are adapted to their environments in ways that help them survive, such as streamlined bodies that aid fish in swimming or thick layers of fat that keep seals warm. An animal's habitat is the place it lives and finds what it needs to survive, like food, water, shelter and mates. Living things depend on each other for food, with plants and some animals producing food (primary producers) and other animals consuming food (

Food chain
Food chains show the transfer of energy from producers to consumers in an ecosystem. Producers, like plants, use sunlight to photosynthesize and produce food. Herbivores then eat the producers, and carnivores eat the herbivores, passing the energy from one organism to the next up the chain. If the producer or any organism in the chain is removed, it disrupts the entire food chain and can cause population declines or extinctions throughout the ecosystem. Humans can negatively impact food chains through activities like pollution, habitat destruction, and overhunting or overfishing. Maintaining healthy food chains is important for balancing populations and preserving biodiversity.

The Fascinating World of Bats: Unveiling the Secrets of the Night
The Fascinating World of Bats: Unveiling the Secrets of the Night
Bats, the mysterious creatures of the night, have long been a source of fascination and fear for humans. With their eerie squeaks and fluttering wings, they have captured our imagination and sparked our curiosity. Yet, beyond the myths and legends, bats are fascinating creatures that play a vital role in our ecosystem.
There are over 1,300 species of bats, ranging from the tiny Kitti's hog-nosed bat to the majestic flying foxes. These winged mammals are found in almost every corner of the globe, from the scorching deserts to the lush rainforests. Their diversity is a testament to their adaptability and resilience.
Bats are insectivores, feeding on a vast array of insects, from mosquitoes to beetles. A single bat can consume up to 1,200 insects in an hour, making them a crucial part of our pest control system. By preying on insects that damage crops, bats save the agricultural industry billions of dollars each year.
But bats are not just useful; they are also fascinating creatures. Their ability to fly in complete darkness, using echolocation to navigate and hunt, is a remarkable feat of evolution. They are also social animals, living in colonies and communicating with each other through a complex system of calls and body language.
Despite their importance, bats face numerous threats, from habitat destruction to climate change. Many species are endangered, and conservation efforts are necessary to protect these magnificent creatures.
In conclusion, bats are more than just creatures of the night; they are a vital part of our ecosystem, playing a crucial role in maintaining the balance of nature. By learning more about these fascinating animals, we can appreciate their importance and work to protect them for generations to come. So, let us embrace the beauty and mystery of bats, and celebrate their unique place in our world.
