Overfishing is a global problem in which humans harvest certain species of fish, almost to the point of extinction. Many of the fish stocks depleted by overfishing are at the top of the food chain. Why would the overfishing of very large fish cause a decrease in the numbers of small fish? The small fish are more likely to die from diseases and parasites.

The small fish live in a mutualistic relationship with the large fish.

The small fish have a greater number of medium-sized predators.

The small fish must compete with each other for fewer food sources.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
