7. Levels of organization
Ecosystem
Levels of organization
Biomes come together to form the Biosphere
Ecosystems comes together to form the Biomes
Communities comes together to form Ecosystems
Populations of different species come together to form Communities
Individuals of the same species form a Population
Species (groups of individual organism)

8. Types of ecosystems

9. Producers = Consumers = autotrophs heterotrophs
Organisms
Producers
Consumers
Organisms that produce their own food
using the Sun’s energy
Organisms that consume others for energy
Producers =
Consumers =
autotrophs
heterotrophs

12. How a food chain differs from a food web?
Food chain smaller than food web

13. Trophic level: the feeding position of an organism in a food chain.
A carnivore that preys on secondary consumers is called a tertiary consumer. A fox feeding on a snake is a tertiary consumer.
fourth trophic level
tertiary consumers
third trophic level
secondary consumers
Carnivores occupy the third and fourth trophic levels. A carnivore that preys on primary consumers is called a secondary consumer. A snake that eats a mouse
is a secondary consumer.
second trophic level
primary consumers
Herbivores occupy the second trophic level. These plant-eating consumers, such as mice that eat seeds, are known as primary consumers.
Producers, such as grass
or algae, occupy the first
trophic level.
First trophic level
producers
