I'm stuck on these questions:

1. A large percentage of the living species on Earth live in the tropical rain forests of the world. Why are so many organisms able to inhabit the rain forest biome? Explain your answer.

2. What sorts of problems so seasonal differences in climate present for the animals and plants in a biome? How do animals and plants adapt to changing seasons?

  1. 1.  The rainforest biome has lots of different niches - (five plant layers) so offer homes / n=habitat to a wide range of species.  All high net primary productivity (ie a lot of green stuff grows per year) means there is large food resource.

    2.  Answers above are good, also you could add growing thick fur / camouflage fur (arctic fox etc).  as for plants, they go dormant (ie drop their leaves) in winter in temperate zones but in the tropics they do not have a dormant period.  Other plants adapt to drought (cactus) and waterlogging (mangrove)


  2. Uhh, I don't know for #1, but for the next one, you can say hibernation and migration. Bears and others hibernate for the winter, and birds migrate to escape the cold. In some biomes, like the Tundra, plants grow very close together, almost in groups, to retain heat.
