Environment and feeding relationships
This document discusses habitats and adaptations. It explains that a habitat is an organism's environment and surroundings. Organisms are adapted to their habitats through physical traits that allow them to survive, such as a rabbit's large ears and hind legs. The document also covers feeding relationships, with producers making food, herbivores eating plants, and carnivores preying on other animals. Predators have adaptations for hunting prey, while prey have adaptations for avoiding predators.
Basic science
This document defines key terms related to ecosystems, including systems, open and closed systems, stability, populations, communities, habitats, niches, producers, consumers, and decomposers. It explains that an ecosystem is a group of living things and their environment that interact, and discusses the roles of different organisms within food chains and ecosystems.
Tabla temasunificantes
This document provides a summary of the eight unifying themes of biology according to a biology class at Universidad de Puerto Rico-Cayey. It lists each theme and provides a brief example of how that theme applies to living organisms. The themes discussed are: 1) New properties emerge at each level of the biology hierarchy. 2) Organisms interact with their environment and each other. 3) Life requires energy transfer and transformation. 4) Structure and function are correlated at all levels of biological organization. 5) The cell is the basic unit of structure and function of organisms. 6) Continuity of life is based on heritable information in DNA. 7) Feedback mechanisms regulate biological systems. 8)
Pyramids
This document summarizes different types of ecological pyramids including pyramids of numbers, biomass, and productivity. It explains that pyramids of numbers show the relative population sizes at each trophic level, while pyramids of biomass show the total mass of organisms. Pyramids of productivity represent the flow of energy through trophic levels, which typically decreases at each level as only 10% of energy is transferred. Examples are given of each type of pyramid along with their advantages and disadvantages. Key concepts around species, populations, communities, niches, habitats, and ecosystems are also defined. Different biotic interactions like competition, predation, symbiosis, commensalism and parasitism are briefly explained
Unit 1 ecology powerpoint 1 revised 2012
The document provides an introduction to an ecological biology class, outlining expectations for students including obtaining handouts, materials needed, and discussing what biology is as a science and discipline. It explores the characteristics of life through an interactive demonstration of determining if an object is alive or not based on observations. The class will focus on studying life and the role of water through examining common characteristics of organisms and using the river as a unifying theme.
Populations and Ecosystems
The document discusses key concepts about populations and ecosystems. It defines the biosphere as the parts of Earth inhabited by life, including biomes like forests and grasslands. Ecosystems consist of living organisms interacting with each other and their environment. Populations are groups of the same species within an ecosystem. Energy flows through trophic levels from producers to primary, secondary, and tertiary consumers. Organisms adapt through natural selection to survive in their environment, and ecosystems change over time through processes like succession. Invasive species can disrupt native ecosystems.
Amensalism (antagonism)
Dr. P. Suganya discusses amensalism, a type of negative ecological interaction. Amensalism occurs when one species is harmed or destroyed while the other is unaffected. There are two main types of amensalism - competition, where a stronger species deprives a weaker one of resources like food or space, and antibiosis, where one species produces chemicals that kill other species sharing its environment while leaving itself unharmed. Examples given include goats outcompeting grasshoppers for food and the fungus Penicillium producing penicillin that kills bacteria without affecting itself.
HEE Chapter 5
This document summarizes key ecological concepts including:
1) The study of ecology examines interactions between organisms and their environments. Environments provide living (biotic) and non-living (abiotic) factors that affect organisms.
2) Organisms have niches defined by their habitat needs and roles. Populations evolve through natural selection acting on genetic variation between individuals.
3) Organisms interact through predation, competition, and symbiotic relationships like parasitism, commensalism, and mutualism.
4) Energy and nutrients cycle through ecosystems, with producers, consumers, and decomposers playing important roles in food chains, webs, and biogeochemical cycles.

Biology 1 Unit 3 notes
This document summarizes key concepts about ecosystems, including:
1) Ecology studies interactions between living things and their environment at different levels of organization, from organisms to ecosystems. Biotic factors are living parts of the environment like plants and animals, while abiotic factors are non-living like sunlight, temperature, and wind.
2) Energy enters ecosystems through producers, mostly plants that use photosynthesis, and flows through food chains of consumers like herbivores, carnivores, and decomposers. Only about 10% of energy is transferred at each trophic level with 90% lost as heat.
3) Matter cycles through ecosystems in biogeochemical cycles like the water, carbon, and nitrogen cycles which move
Chapter 2 Slides
The document discusses interactions within ecosystems. It defines biotic factors as living things like plants and animals, and abiotic factors as non-living things like air, water, and temperature. Ecosystems contain habitats where many organisms live and interact, and contain both biotic and abiotic components. Ecosystems can vary in size from small areas like tide pools to large areas like entire forests. Within ecosystems, organisms depend on abiotic factors, and populations of organisms interact to form communities of biotic factors.
Food chain
A food chain describes the transfer of energy from organism to organism in an ecosystem. Primary producers like plants trap solar energy through photosynthesis and are eaten by primary consumers like herbivores. These primary consumers are then eaten by secondary consumers such as carnivores or omnivores. Tertiary consumers may also exist and consume secondary consumers. Food chains interconnect to form complex food webs as most organisms have more than one food source. Energy from the sun is passed from producers to consumers in a food chain.
Biotic Interactions
- Biotic interactions include predator-prey relationships, plant-herbivore relationships, competition, and symbiosis. Abiotic interactions involve interactions between organisms and environmental factors like temperature, light, and nutrients.
- Density-dependent factors like predation and competition cause populations to decrease when densities are high and increase when densities are low. Density-independent factors like fires and floods impact populations independently of their densities.
- Predator-prey relationships can follow stable, cyclical, erratic, or extinction patterns depending on factors like carrying capacity and reproduction rates of both species. Predators benefit from food while prey benefit from reduced competition.
Bioeradication white paper
This is a short paper on Bioeradication containing definitions and theory. It is a work in progress which is being further developed throughout the field season of 2015 and ... .
Energy flow (bd mod)
All ecosystems depend on energy from the sun which is converted to chemical energy by producers like plants through photosynthesis. This energy is transferred between trophic levels in a food chain or food web, but around 90% is lost at each level. The inefficiency of energy transfer means longer food chains are less viable as more energy is lost, limiting the productivity of the ecosystem.
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
BiologyExchange.co.uk Shared Resource
This document discusses ecosystems and sustainability. It defines key ecosystem concepts like producers, consumers, decomposers, trophic levels, food chains and food webs. It explains how energy and nutrients cycle through ecosystems and how human activities like using pesticides, fertilizers and different forestry practices can influence these cycles and food chains. Succession and factors affecting population sizes are also covered. The document advocates for sustainable forest management techniques like rotational coppicing to balance resource use and conservation of biodiversity.
Symbiotic relationship
Symbiotic relationships are interactions between species that can be beneficial or harmful. Obligate symbiosis requires both organisms for survival, while facultative symbiosis is a choice. Predation is when one organism hunts another for food, including herbivory, carnivory, fungivory, and detritivory. Commensalism benefits one organism without affecting the other, like epiphytes on tree hosts. Protocooperation is a form of mutualism where organisms mutually benefit but do not require each other, such as root grafts between trees or plants and their pollinators. Allelopathy refers to the chemical inhibition of one plant species by another through allelochemicals released into the environment
Module 1 and 2 review
This document discusses key concepts in ecology, including abiotic vs biotic factors, the MRS GREN criteria for determining if something is living, components of ecosystems like habitats and communities, parts of a food chain including producers, consumers, and decomposers, and different types of relationships between organisms like mutualism, commensalism, and parasitism.
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.
Unit9 Living Things in their Environment
This document provides an overview of living things in their environment. It discusses environmental factors, adaptations of organisms, how organisms change their environment, populations, and communities. Specifically, it defines abiotic and biotic factors, limiting factors, and different types of adaptations including morphological, physiological, and behavioral adaptations. It also describes population dynamics including exponential and stationary growth phases. Finally, it examines community concepts such as ecological succession, soil composition, and interspecific relationships including mutualism, parasitism, predation, and competition.
Mutualism, Species Abundance, and Diversity
This document provides an outline and introduction for a chapter on mutualism, species abundance, and diversity. It discusses different types of mutualistic relationships between plants and fungi (mycorrhizae) and corals and algae. It also covers topics like species abundance patterns, species diversity indices, environmental complexity and niches, and the effects of disturbance on diversity.
Ecological pyramids
Ecological pyramids graphically represent the trophic structure and energy flow in an ecosystem. They typically have producers at the base and apex consumers at the top. There are three main types of ecological pyramids: number, biomass, and energy. Pyramids of number show the decreasing number of individuals at higher trophic levels due to factors like population growth rates and predation. Biomass pyramids represent the total weight of organisms, which usually decreases upward but can sometimes be inverted. Energy pyramids illustrate the reduction of available energy at each trophic level as around 90% is lost as heat at each transfer.
Chapter 4 interdependence among living organisms and the envirronment
This document discusses interdependence among living organisms and the environment. It covers topics such as species, populations, communities, habitats, ecosystems, interactions between living organisms including predator-prey relationships, symbiosis, competition, food webs, and the importance of photosynthesis. Photosynthesis produces oxygen and food for animals while using carbon dioxide, and the carbon and oxygen cycles help regulate gas levels on Earth. Conservation efforts aim to preserve natural resources for future generations.
IB Biology 5.1 communites and ecosystems
This document discusses key ecological concepts including species, habitats, populations, communities, ecosystems, trophic levels, food chains, and food webs. It defines species as groups of organisms that can interbreed, habitats as the environment where a species lives, and populations as groups of the same species in a common area. Communities are defined as groups of interacting populations in a shared habitat. Ecosystems include both biotic and abiotic components. Organisms are classified as autotrophs, which produce their own food, or heterotrophs, which consume other organisms or organic matter. Food chains and webs illustrate the trophic or feeding levels and energy flow through an ecosystem.
Energy flow and nutrient cycles
The document discusses energy flow through ecosystems. It explains that:
1) Solar energy is absorbed by plants and used to produce food through photosynthesis.
2) Animals obtain energy by eating plants or other animals. As they are more active, there are typically more plants than animals.
3) When organisms die, decomposers like bacteria break down their bodies and recycle the energy and nutrients.

Ecological pyramid
Ecological pyramids graphically represent biomass or productivity at trophic levels in an ecosystem. There are three main types: number, biomass, and energy. Pyramids of number show the population size at each level but don't account for size. Biomass pyramids depict the mass at each level and are more accurate but require killing organisms. Energy pyramids represent energy transfer between levels and always slope upwards due to energy loss, allowing ecosystem comparisons over time. Pyramids are important for understanding ecosystem structure and function but have limitations as food webs are more complex than simple chains.

What is ecology 2012
Ecology is the study of the interactions between living things and their physical environment. Abiotic factors include non-living elements like temperature, light, and moisture that affect organisms. Biotic factors refer to living things that directly or indirectly impact the environment. Ecosystems consist of communities of interacting organisms and their physical environments. Within ecosystems, autotrophs like plants produce food, while heterotrophs consume other organisms or their byproducts. Symbiotic relationships between different organisms can be mutualistic, commensal, or parasitic.

Biology
Ecology is the scientific study of interactions between organisms and their environment. Ecologists seek to explain life processes, interactions, adaptations, movement of materials and energy through communities, successional development of ecosystems, and abundance and distribution of organisms. Biodiversity describes genetic, species, and ecosystem diversity and can be indexed in many ways. Habitats are defined by environmental factors that determine the type of community formed. Population ecology studies population dynamics and how populations interact with their environment.

- Ecology provides the scientific foundations for fields like agriculture and helps predict environmental impacts.
- Ecosystems consist of biotic (living) and abiotic (non-living) components that interact. Energy from the sun flows through food chains/webs between organisms, while nutrients are recycled through biochemical cycles.
- Pyramids of numbers, biomass, and energy are used to quantify energy and nutrient transfer between trophic levels in an ecosystem. The pyramids typically decrease at higher trophic levels due to inefficiencies in energy transfer between levels.
Ecology Rev.ppt
This document provides an overview of key concepts in ecology. It defines ecology as the study of interactions between organisms and their environments. The environment contains biotic factors like other living things, and abiotic factors like climate and soil. Organisms have niches defined by how they interact with biotic and abiotic factors. Ecosystems involve complex food webs of producers, consumers, and decomposers that transfer energy and cycle nutrients. Species also engage in relationships like predation, competition, and mutualism.
Ecology Rev.ppt
This document provides an overview of key concepts in ecology. It defines ecology as the study of interactions between organisms and their environments. The environment contains abiotic (non-living) factors like climate and biotic (living) factors like other organisms. Organisms have niches in ecosystems based on their roles as producers, consumers, or decomposers in food webs and energy pyramids. Species interact through relationships like predation, competition, and symbiosis. Energy and matter cycle through ecosystems, getting lost at each trophic level according to the 10% law.
Ecology Rev.ppt
This document provides an overview of key concepts in ecology. It defines ecology as the study of interactions between organisms and their environments. The environment contains abiotic (non-living) factors like climate and biotic (living) factors like other organisms. Organisms have niches within ecosystems based on their roles as producers, consumers, or decomposers. Energy and matter transfer between trophic levels according to food chains and webs, following the 10% law where only 10% of energy is transferred between levels. Relationships like predation, competition, and symbiosis influence populations and communities within ecosystems.
Ecology-Rev.ppt
This document provides an overview of key concepts in ecology. It defines ecology as the study of interactions between organisms and their environments. The environment contains abiotic factors like climate and biotic factors like other living things. Organisms have niches defined by their habitats and roles in food webs. Food webs show how energy passes between trophic levels from producers to various consumer levels, and how pollutants can biomagnify up the food chain. Species also interact through predation, competition, symbiosis and coevolution.

Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into glucose and oxygen through the chemical reaction of 6CO2 + 6H2O + light energy yielding C6H12O6 + 6O2. Cellular respiration is the process by which organisms break down glucose to release energy through the chemical reaction of C6H12O6 + 6O2 yielding 6CO2 + 6H2O + energy. In a chemical reaction, reactants are the starting substances and products are the substances formed.
Model vocabulary book photosynthesis
Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into glucose (sugar) and oxygen. The chemical reaction is: 6CO2 + 6H2O + light energy → C6H12O6 (glucose) + 6O2. Cellular respiration is the process by which organisms break down glucose to release energy. The chemical formula for respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy. Reactants are the starting substances in a chemical reaction, while products are the substances formed.

Abiotic cycles
This document discusses the abiotic cycles that recycle matter on Earth to sustain life, including the nitrogen cycle, water cycle, and carbon dioxide/oxygen cycle. These cycles move matter like nitrogen, water, carbon, and oxygen through ecosystems as plants, animals, and microbes break down waste and each other, and as atmospheric gases dissolve and circulate through environments. The recycling of matter through these natural cycles is essential to maintaining life on our planet.
