What is ADAPTABILITY or TOLERANCE or RESILIENCE.
200
They point towards the flow of energy.
Which direction do the arrows point within a food chain or food web?
200
Nitrogen-fixing bacteria live in the roots of leguminous plants and convert atmospheric nitrogen into a form the plants can use. The plants provide the bacteria a place to live and access to carbohydrates produced through photosynthesis.
What is an example of MUTUALISM?

A hawk and an owl live in the same ecosystem. One hunts during the night while the other hunts during the day. Because they both have different jobs, they do not compete with each other for resources.
What is an example of a NICHE?
200
A slow, progressive change in an environment that does not begin with any fertile organic material. It could take millions of years.
What is PRIMARY SUCCESSION?
200
When animals and shade-tolerant trees can survive.
What is the CLIMAX COMMUNITY in primary succession?
300
It is lost as heat to the environment.
What happens to the 90% of energy not reserved between trophic levels?

Other-eater.
What is a HETEROTROPH?
300
Biosphere, biome, ecosystems, community, population, species
What are the levels of ecology?

An example would be that a kangaroo rat can survive without drinking any water, but it must obtain moisture from its food. This is to its benefit in its native environment.
What is an example of SELECTIVE-ADAPTATION for a desert environment?
400
They show a more detailed model of how a variety of food chains react together within an ecosystem, rather than showing one singular chain of events.
What is a benefit of a food web over a food chain?

What would examples of LIMITING FACTORS in a desert ecosystem be?
500
They act as detritivores, decomposing the leftover organic matter that other organisms didn't consume. This reintegrates that material back into the ecosystem.
What is the function of Fungi?

The frogs in the tank on my desk hunt the crickets I drop in there from time to time.
What is an example of PREDATION?
500
Anything that is photosynthetic or chemosynthetic.
What type of organisms are AUTOTROPHS?
500
Because they contain photosynthetic algae (making them autotrophs) and fungi (making them decomposers).
Why are lichen the pioneer species of primary succession?
500
When soil is already present this process goes much faster.
What is SECONDARY SUCCESSION and how does it differ from primary succession?
