As a result of the absence of plants in the meadow, the rabbit population will probably a) decrease in size. b) increase and flourish. c) increase reproduction. d) switch to a different type of food.

A) decrease in size.

Explanation:

A food chain is a linear sequence of transfer of food and energy when one organism is consumed by the other organism. A meadow is a field of grass. The grass is included as a producer in a meadow food chain. As they are capable of producing their own food by the process of photosynthesis. The population of rabbit which are herbivores is largely dependent on grass in meadow food chain as a source of food. In the absence of grass the population of rabbit will probably decrease in size.

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.
