Answer 1

Many factors affect the survival and population size of a species within an ecosystem. The symbiotic relationships that organisms have with each other also influence populations. If the symbiotic relationship is beneficial to both species, like in mutualism, then their populations may remain steady or increase. If a species is negatively affected by other species, such as in competition, predation, and parasitism, their population size may decrease.

Limiting factors such as access to food, presence of disease, symbiotic relationships, and availability of mates are all biotic factors since they are living factors. Water, sunlight, air pollution, shelter, climate, and weather are all abiotic limiting factors that influence populations.

Answers used: ecosystem, mutualism, parasitism, biotic, abiotic.
