What are some "characteristics" (life-history traits) of species that make them vulnerable to extinction/endangered status (there's a little diagram/table that we've gone over). for instance, a low reproductive rate is one of them.

Over exploitation by people

Habitat loss

Pollution

and urbanilazation

Explanation:

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.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
