How do biotic factors affect population?
Biotic factors refer to the living or once-living organisms in an ecosystem and their impacts such as predation, competition, food supply, human impacts and parasites. Environmental factors such as rainfall, climate, predators, shelter and food availability can change.
How do abiotic factors affect population size?
The carrying capacity depends on biotic and abiotic factors. If these factors improve, the carrying capacity increases. If the factors become less plentiful, the carrying capacity drops. If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity.

What happens to abiotic factors when biotic populations increase?
Explain what happens to abiotic factors when biotic populations increase? The abiotic factors can become scarce. Explain how organisms compete for abiotic factors in an ecosystem. … List two biotic factors that could survive in a desert ecosystem and explain which abiotic factors they would depend on and why.
What are biotic and abiotic factors that limit population size?
A. What are the biotic and abiotic factors that limit population size? The biotic and abiotic factors that limit population size are space, food, shelter, water, climate, competitive exclusion, and temperature.
How do biotic and abiotic factors affect crop production?
Biotic factors like insects, rodents, pests, and many more spread the disease and reduce crop production. … Abiotic factors like humidity, temperature, moisture, wind, rain, flood and many more destroy the crop raise. Abiotic factors like hot, cold, drought, salinity, etc. affect crop production.
How do biotic factors affect species distribution?
They can also influence the distribution of organisms in an ecosystem. grazing – too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity. predation – a reduction in predators can lead to an increase in prey.
How do biotic factors affect plants?
Herbivores with significant deleterious effects on crop growth and yield are called pest. Damage caused by these biotic factors are varied such as death of the entire plant or organs, reduced root, stem, leaf or inflorescence mass, total defoliation, bores and holes on plant parts, and other marks of feeding.
How do abiotic factors affect species distribution?
Inorganic nutrients, soil structure, and aquatic oxygen availability are further abiotic factors that affect species distribution in an ecosystem. The same is true for terrestrial factors, such as wind and fire, which can impact the types of species that inhabit regions exposed to these types of disturbances.
