Male house sparrows (a bird species) sing a different song than do male tree sparrows (a different bird species). based on this information alone, what type of prezygotic isolation mechanism might be acting to keep the species separate?

Behavioral isolation

Explanation:

The prezygotic isolation mechanisms are ecological, temporal, mechanical, behavioral and gametic. The mechanism shown here is behavioral because the birds sing a different song and their songs are used to attract mates as part of their mating behaviors. The different songs attract different species, thus the females of each species will only be attracted to the song of their own species, preventing mating between different species of birds.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
