Energy Transfer in Ecosystem Vocabulary Trophic = nutrition –Autotrophs –Heterotrophs
Heterotrophs Consumers 1. Scavengers feed on the tissue of dead organisms (both plans and animals)
Heterotrophs Consumers 2. Herbivores eat ONLY plants.
Heterotrophs Consumers 3. Carnivores eat ONLY animals.
Heterotrophs Consumers 4. Omnivores eat BOTH plants and animals
Heterotrophs Decomposers absorb any dead material and break it down into simple nutrients or fertilizers
Transfer of Energy
Trophic Levels… …represent different levels in a food web.
Food Webs We represent the energy flow from one trophic level to another as a food web. (Most organisms eat more than one different species.)
Food Web Notice that the direction the arrow points The arrow points in the direction of the energy transfer, NOTwhat ate what.
Ecological Pyramid 1. Which level has the most energy? 2. Which level has the most organisms? 3. Which level has the fewest organisms? 4. Which level has the least energy?
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.

Topic 5.1 / Option G.1 Community Ecology 3 Food Webs and Trophic Structure Assessment Statements:
Ecology The study of interactions that take place between organisms and their environment.
Section 13-3 & 13-4 Energy & Food Chains Section 13-3 & 13-4 Energy & Food Chains Write everything that is underlined.
EcologyEcology: the study of interactions that take place between organisms and their environment Ecology.
Ecology. Ecology is the study of the interactions of living organisms with one another and with their physical environment (soil, water, climate…) ECO.
Ecology Movement of energy. Know the 3 Es Ecology = the study of the relationship between organisms and their environment. Ecosystem = all the living.
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.
How are species on our planet connected?. Layers of our Planet Geosphere: solid part of earth that consists of soil, rock and sediments. Geosphere: solid.
Energy Flow in Ecosystems 3.4. Energy Flow When an animal eats a plant, energy is transferred from plant to animal The same thing happens when an animal.
Ecology. Ecology Ecology is the study of interactions between different kinds of living things and their environment. Ecology is the study of interactions.
ECOLOGY The study of interactions of organisms and their environment.
Producers, Consumers, and Decomposers 3.3. Producers All living things get energy from food Producers make their own food They are called Autotrophs Most.
Communities!. All around us are organisms (living things) living in communities, e.g. in NZ native bush. Each species has its own population within the.
Ecology By Ashley Olsen. What is ecology? Ecology is Ecology is the study of the relationship between the environment and living organism Their interactions.
Energy Flow Through an Ecosystem Food Chains, Food Webs, Energy Pyramids.
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.
Food Webs. Community All organisms inhabiting a particular area.
Students will examine the dependence of organisms on one another and their environments.
