Anything living in an ecosystem is considered
Biotic
Matter (CYCLES or FLOWS) through an ecosystem.
Cycles
The amount of energy that moves from one trophic level to the next
10%
Organisms that eat both meat and plants are called
Omnivores
Grasshoppers are considered (PRODUCER or CONSUMERS)
Consumers
The non-living parts of an ecosystem
Abiotic
Any form of water that falls from the clouds is called
Precipitation
All energy on Earth, directly or indirectly, comes from the ______________.
Sun

Photosynthesis
The fox in this food web can be classified as a (heterotroph or autotroph)
Heterotroph

What would happen to the population of owls if the mouse was removed from the food web?
The population of owls would decrease because there would be less available food for them.
This contains all the biotic and abiotic factors in a given area.
Ecosystem
This organism is a (PRODUCER, OMNIVORE, DECOMPOSER, or CARNIVORE)
Decomposer
False, abiotic factors are things that are not alive and were never alive.
These organisms go through nitrogen fixation, which turns nitrogen gas into a usable form.
Bacteria
If the grass contains 5000 units of energy, how much energy do the primary consumers have available at their trophic level?
500 units of energy
What do decomposers do?
Recycle nutrients from dead organisms back into the environment.
What would happen to the snake population if the eagles were removed from the food web?
The snake population would increase because the eagles are predators of the snakes.
Name three abiotic factors in this picture.
Sun, Water, Air
The evaporation of water from plants is called
Transpiration
If autotrophs have 35,000 units of energy available to them, how much energy would secondary consumers have?
350 units of energy
Secondary consumers = organisms that eat herbivores
Heat being trapped by carbon dioxide and other gases in the atmosphere that helps keep the planet warm
Greenhouse Effect
