Ahousing development is situated near a river that flows into a bay. which of the following is an abiotic factor on land that would directly affect the marine ecosystem in the bay? the number of houses using central air conditioning the amount of sunlight reaching the area the height of the trees in the neighborhood the amount of fertilizer runoff coming from lawns

The amount of fertilizer runoff coming from lawns

An abiotic factor is a non-living component of the ecosystem. A list of abiotic factors includes water, sunlight, soil, atmosphere, temperature, wind, climatic conditions and chemical elements. These abiotic factors directly or indirectly affects the biotic or living components of the ecosystem.  A housing development is situated near a river that flows into a bay. Here, fertilizer is a abiotic factor which is being runoff from lawns because fertilizers usually contains chemicals that can contaminate the water of the bay. The chemicals present in the fertilizers can be consumed by aquatic animals hence, can have detrimental effect on them.    

Therefore, the amount of fertilizer runoff coming from lawns is an abiotic factor on land that would directly affect the marine ecosystem in the bay.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
