Weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
<h3>What are the biotic and abiotic factors of an ecosystem?</h3>
Biotic factors are each of the living organisms of an ecosystem and abiotic factors are all non-living ones such as organic and inorganic substances in the system as well as environmental conditions.
Weather, climate, and seasons could affect these factors in altering the distribution of species, but would also decrease primary production, which would affect survival and growth.
Therefore, we can conclude that the weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
