Community All organisms inhabiting a particular area
Autotrophs Producers – self feeding Produce their own organic material Green plants Called primary producers
Heterotrophs Consumers Organisms which must consumer organic material to obtain energy
Consumers Primary Consumers Secondary Consumers
Primary Producers Control the rate at which producers convert sunlight to chemical energy in organic matter, or biomass Determines the energy budget for ecosystems
Decomposers Also called detritivores Acquire energy from all trophic levels waste products and dead material
Food Chain Pathway of food within a community Links energy and nutrients between producers, consumers and decomposers Divided into trophic levels
Trophic Structure Every community has a trophic structure Trophic levels increase as you go up the food chain
Energy levels decrease as you go up the food chain
Only approximately 10% of the energy stored at each trophic level is available at to the next level
Food Web A series of interconnected food chains
Biomass A measure of the dry weight of an organism is a rough measure of the energy it contains A measure of the population multiplied by the weight of an average individual in it
Ecology. What is Ecology? Ecology is the study of interactions among organisms and between organisms and their environment. Ecology is the study of interactions.

What is Ecology?. * Ecology is the study of interactions among organisms and between organisms and their environment.
Food Chains and Food Webs Energy Flow in Nature. Energy Roles An organisms energy role in an ecosystem may be that of a producer, consumer, or decomposer.
Energy Flow through a Food Chain. ENERGY FLOW Autotrophs vs. Heterotrophs
EcologyEcology: the study of interactions that take place between organisms and their environment Ecology.
Energy in Ecosystems Food Chains, Food Webs and Energy Pyramids Courtesy:
2.1 – Energy Flow in Ecosystems. Energy flow in ecosystems Biomass is the total mass of all living things in a given area. – Biomass can also refer to.
Ecology. Ecology is the study of the interactions of living organisms with one another and with their physical environment (soil, water, climate…) ECO.
Energy flows through ecosystems. Chapter 1 Section 3.
Part 2 - Food Chains and Webs: If an ecosystem is to be self-sustaining it must contain a flow of energy. Those life activities that are characteristic.
Topic 5.1 / Option G.1 Community Ecology 3 Food Webs and Trophic Structure Assessment Statements:
Ecology Concepts F Ecosystems. Relationships, I F Trophic structure / levels ~ feeding relationships in an ecosystem F Primary producers ~ the trophic.
Ecology Movement of energy. Know the 3 Es Ecology = the study of the relationship between organisms and their environment. Ecosystem = all the living.
Energy Flow in an Ecosystem. Energy Transfer Energy is the ability to do work 3 main paths in which energy flows Producers Consumers Decomposers.
