explain how weather,climate,and seasons could affect the biotic and abiotic factors of an ecosystem
Weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
What are the biotic and abiotic factors of an ecosystem?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.

Answer:
RED and BLUE
Explanation:
Special pigments in chloroplasts of plant cells absorb the energy of certain wavelengths of light, causing a molecular chain reaction known as the light-dependent reactions of photosynthesis. The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).
