A temperate grassland and a tropical rain forest are both climax communities. What accounts
for the discrepancy in plant species in these 2 biomes?

Tropical rain forest

Explanation: Tropical rain forest covers the largest area of terrestrial biome. This biome has highest number of plant and animal species.

This has a variety of plant and animals that makes a rich biodiversity. This biome is a source of many pharmaceutical drugs. The biome can also be a source of wooden logs, various types of chemical compounds derived from the animal species and plant species as well.

This biome is a home for many of the animal and source of food as well.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
