How do wind patterns occur?

when and how it reproduces, the food it eats, and the way in which it obtains food.

What are examples of biological aspects of an organism's niche?

What is an example of a human caused disturbance?

wind, and fire. disturbance goes and interrupts this progress again.

What can interrupt the progress of succession?

parasitism is different from commensalism because it is something that lives in or on something and harms it, while commensalism is something that benefits from something that doesnt get harmed or helped.

How is parasitism different from commensalism?

symbiotic relationship in which both species benefit from the relationship

parasitism.

symbiotic relationship in which both species benefit from the relationship

mutualism.

primary succession is when there is no disturbance and hasnt been destroyed at all, and secondary succession is when it has been only partially destroyed by disturbances.

What a difference between primary and secondary succession?

wide range of conditions, within the many biomes

What does climate produce (section 4)?

nitrogen, phosphorus, oxygen, hydrogen.

The nutrient availability of aquatic ecosystems depends on the amount of what?

tundra and the desert.

Which two biomes have the least precipitation?

zooplankton has to be fond in the photic zone, because it has to have the light penetrating through the waves.

Would you find zooplankton in the aphotic, benthic zone of an ocean? Why or why not?

How are the North and South Poles classified?

water is covering the surface only certain times of the land, while it always flows in a lake or pond.

What is one way a freshwater wetland differs from a lake or pond?

Estuaries support a lot of biomass, which makes them commercially valuable. different variety of fish.

Why are estuaries commercially important?

the mixture of water, it is a mix of saltwater and freshwater. certain type of fish species, also known as a lot of biomass with not alot of variety.

What makes estuaries unique?

special kind of wetland where a river meets the sea; referred to as saltwater wetlands.

Define estuary.

coastal

A freshwater ecosystem that can purify water and help prevent flooding by absorbing large amounts of water is a

A species' Tolerance is its ability to survive and reproduce under a range of environmental conditions.

microclimate is related to climate because it differs from the main climate around a little bit
