The nitrates in nitrogenous waste reduce the oxygen carrying capabilities of the haemoglobin in the blood of animals. Since plants do not have haemoglobin they can absorb it to help them make proteins.

One reason that all living things need nitrogen is because DNA consists of deoxyribose, a phosphate group, and nitrogenous base pairs ( Adenine, Tymine, Guanine, and Cytosine). Without the nitrogenous bases, genectic material could not exist, therefore there would be no life.
Aristotle divided living things into plants and animals and then subdivided animals into land, water and air. He subdivided plants into small, medium, and large. This caused problem because some animals traveled by walking, swimming and flying.
plants and animals
Plants get their energy through photosynthesis, and animals get their energy by consuming plants or other animals.
Plants give off oxygen for animals to breathe and animals exhale CO2 which plants use to make glucose and take out more oxygen. Then animals eat plants to get glucose and when they die or defecate, they leave nitrogenous wastes which are eaten by plants (absorption through roots).

Dehydration
For plants it was turning sunlight into chlorophyl. For animals ,that depends on which animal or organism the question pertains to. The main problem here is with the ambiguity of the question.
This process is known as nitrogen fixation. Soil bacteria convert nitrogenous wastes into nitrates through a process called nitrification. Plants then absorb these nitrates to fulfill their nutrient requirements.
Plants do not directly absorb nitrogenous waste like urine; however, they can benefit from the nutrients it contains. When urine breaks down in the soil, microorganisms convert its nitrogen compounds into forms that plants can uptake, such as ammonium and nitrate. Thus, while plants don't absorb urine directly, the nutrients can be made available through decomposition and microbial processes.
Dead plants and animals are helpful because when they decompose, the bacteria help release certain nutrients into the ground that plants thrive on. Sort of like if one plant releases nitrogen into the soil and then is planted next to a plant that thrives on it.

Forest fires are a problem and some certain bugs are dangerous to plants.
What possible problem does that solve?
it can developed by fossils of animals and decayed plants. or there are some alternative ways to improve the land. you can plant clover in your garden. because there are some special nitrogenous bacterias that produce nitrogen for plant
Animals excrete nitrogenous waste products, such as urea or ammonia, that result from protein metabolism. Unlike animals, plants primarily eliminate excess water and certain minerals through transpiration and root exudates. Additionally, animals may release carbon dioxide through respiration, while plants utilize carbon dioxide for photosynthesis. Thus, the specific waste products and metabolic processes differ significantly between the two kingdoms.
