A group of different species living together in the same area.
Community
These organisms form the base of every energy pyramid.
Producers
A tick feeding on a deer is an example of this type of relationship.
Parasitism
Trees remove this gas from the atmosphere and store it in their tissues.
Carbon Dioxide
Coral reefs are found in this type of water environment.
Warm, shallow ocean water.
All living and nonliving components interacting in one area.
Ecosystem
If producers capture 50,000 kcal of energy, about this much energy would be available to primary consumers (10% rule).
5,000 kcal
When both organisms benefit, such as ants protecting a plant while living in it, the relationship is called this.
Mutualism
Cutting down forests decreases this important ecological process.
carbon sequestration
Octopus
The global region that includes all ecosystems on Earth.
Biosphere
In a food chain: grass → grasshopper → frog → snake, this organism is the secondary consumer.
The frog
If prey numbers increase, predator numbers will usually do this shortly after.
Increase
Using wood to make long-lasting furniture helps reduce atmospheric carbon because it does this.
Stores carbon for a longer time
This animal has the longest migration of any mammal.
Gray whale
A single species of fish living in a lake would be classified as this.
Population
Energy decreases at higher trophic levels because most energy is lost as this.
Heat
A sudden drop in predators could cause prey populations to do this.
Increase rapidly
An invasive species that consumes native plants will most likely cause this effect on biodiversity.
Decrease in biodiversity
A baby owl is called this
Owlet
If lake trout decrease and affect birds that eat them, this level of organization is being impacted.
Community
If algae-eating fish are removed from a reef, this will most likely happen to algae populations.
They will increase.
The maximum population size an environment can sustainably support is called this.
Carrying capacity
Before reintroducing an endangered species into the wild, scientists perform small controlled tests to reduce this type of risk.
Ecological failure
This big cat cannot roar but can purr loudly
Cheetah
