1. Why do unrelated plants often assume the same growth form in different parts of the world?
Unrelated plants often assume the same growth form in different parts of the world because of similar environmental conditions, physical structure of the plant, myriad interactions of species, chance and history, evolution leading to unique biomes.
2. Which types of environmental conditions limit the distributions of plants?
Cold and dry temperature makes it hard for plants to grow. Tundra, located at the polar where annual precipitation is low, with cold winters, short time for summer. It limits the distributions of plants with no trees and low vegetation.

Most of these will be discharge from the body as waste products. Plus, energy escapes as metabolic heat when consumers from one trophic level are consumed by consumers from the next.
7. How do ecologists distinguish between gross primary production and net primary production?
Gross primary production is the total energy assimilated by primary producers through photosynthesis. Net primary production is the energy that remains in the primary producers after take into account of an organism’s respiration and heat loss. This is the energy available to consumers in plant biomass. The difference between the gross primary production and net primary production is due to the energy lost to respiration.
8. Why do different plant diets result in very different assimilation efficiencies for herbivores?
Different plant diets result in very different assimilation efficiencies for herbivores because there are different portions of cellulose, lignin, and other materials within the plants. For example consuming seeds might get more energy than consuming decaying wood for
