Biosphere 2:

Which of the following is the correct organization of life?

Which biome description is correct?

The range of tolerance for an organism might be:

Carbon dioxide in the atmosphere is:

In order for nitrogen to be usable for other life it must first be:

Using an example such as spring wildflowers and rainfall, explain the terms environmental gradient and range of tolerance.

List the steps involved in the nitrogen cycle. What would happen if a wildfire burned so hot that it sterilized the soil, killing all the microbes?

You are designing a habitat for living on another planet, about the same size as Biosphere 2. Do you want several small biomes or one large biome? Justify your answer, using terms such as habitat, nutrient cycles, and biomass.

You are studying a small island with the following characteristics. It has one type of grass and one type of tree. It has only four types of small invertebrates, one type of lizard, and a seed-eating mouse. It has a worm that feeds on decaying leaves and some soil bacteria for decomposers. Draw your island biome, showing how carbon will move.

A large hawk reaches the island described in question 4. Given your biome’s size, and the amount of carbon-based biomass, is there enough carbon available for the hawk to live on the island? Explain.

You are studying a pocket mouse which lives in an underground burrow where it stores seeds. Make a list of biotic and abiotic things that might be limiting factors to its survival.
