Water in the soil is held tightly by adhesive forces between the water molecules and the mineral content in soil particles - in the microspores.
Explanation:
While water passes through the macrospores of soil by gravity, water passes through the microspores mainly by cohesion between the water molecules and adhesion between the water molecules and soil minerals. The more surface area for the minerals in the soil (due to finer particle sizes) the higher the water retention rate of the soil. This is why soil with more humus (like silt and clay) retains water more than soils like sand.

Chloroplast is responsible for using light energy to produce sugar. It is located at the top of the leaf because that's where it will absorb the most light while it's still being protected from damage by the cuticle and the epidermis
Glucose or sugar are produced during photosynthesis.

The relationship between population growth and resources is inverse; as one goes up the other goes down.
Explanation:
An inverse relationship is one where when one variable is affected positively, the other is negatively impacted, and vice versa. In other terms, when one variable increases the other decreases.
When population growth increases, the strain on the resources increases, due to increased competition, and hence the resources decrease. This is why ideally apopulation cannot grow indefinitely because resources are always limited. The population growth will start to levels off as it reaches carrying capacity. When the resources become depleted the population growth plummets.
