Biome HW: Part 1

Freshwater: What then happens to the profundal zone?

Its just a lower layer in the bottom of the pond/lake/river that mostly contains alge and plankton that sinks down to the bottom. It rarely sees light due to the thick penetration.

Marine: How does such a wide variety of animals live in a reef?

Reefs are excellent grounds for a great variety of wildlife to breed and survive. Plants like coral and seagrasses allow organisms and fishes to thrive and provides shelter at the same time.

Desert: How exactly are deserts hostile?

It could be hostile to unprepared humans due the extremely high temperatures and lack of fresh water available. Extremely hot in the daytime and extreme cold during the night.

Forest: How do plants as old as 100 years old survive in forests?

Most forests are under conservation and being protected by wildlife officials Studies have shown forests must be 150 to 200 years old before the appearance of some species of lichens. Certain herbaceous plants require from 40 to 150 years to rejuvenate, and will never recover in a forest with a logging cycle of 100 years or less. Studies done on forests 90 years after a major event, such as a clear-cut, have found no evidence of the recovery of vernal herbs normally expected in the area. Many plants disperse at extremely slow rates, and once they are eliminated from an area, it may take thousands of years, and the right habitat, for them to return

Grassland: Frequent fires in grasslands?

Tundra: Due to global warming how would plants and wildfire learn to adapt in warmer temperatures?

It's likely that most of the wildlife would not survive and the vegetation would likely die out.
