Chapter 3: How Ecosystems Work Section 3.1: Energy Flow in Ecosystems
Life depends on the sun. Plants, algae, and some types of bacteria capture solar energy and store it as food.
Almost all organisms get their energy from the sun.
Organisms that are able to make their own food are called producers.
Producers are also called autotrophs.
Another type of organism found in the ecosystem is the consumer. Consumers are organisms that get their energy by eating other organisms.
Consumers are also called heterotrophs.
Four types of consumers 1. Herbivores 2. Carnivores 3. Omnivores 4. Decomposers
Herbivores are consumers that eat only producers.
Carnivores are consumers that eat only consumers.
Omnivores are consumers that eat both consumers and producers.
Decomposers are consumers that get their food by breaking down dead organisms.
Consumers get their energy from food by the process called cellular respiration. Cellular respiration is the process of breaking down food to yield energy.
Each time one organism eats another organism, a transfer of energy occurs.
We can trace the paths energy follows as it travels through an ecosystem by studying food chains, food webs, and trophic levels.
A food chain is a sequence in which energy is transferred from one organism to the next as each organism eats another.
A food web shows many of the feeding relationships in an ecosystem.
Trophic levels are each step in the transfer of energy through an ecosystem.
Each trophic level consumes 90 percent of the energy present – only 10 percent is passed onto the next level.

What is Energy?. Energy is the capacity for action/doing work.

Energy Flow In An Ecosystem Unit 11 - Ecology. Producers The most important part of an ecosystem Without a constant energy source, living things cannot.
Energy Flows Through Ecosystems Sun: Makes all energy on Earth. Producers: Make their own food. Consumers: Get their food by eating other organisms. Decomposers:
