Explanation:

Q.1

A species is a group of organisms that can reproduce and have fertile offspring. A population is a group of the same species in an area, biodiversity is the variety of life, and a niche is an organism's role. So the correct answer is the one defining species.

Biodiversity refers to the richness and variety of all life forms, species, and ecosystems on Earth. Species is a single group, population is a group of one species, and niche is a role. So the term for this variety is biodiversity.

Tropical forests have warm, wet climates with stable conditions, allowing for a huge variety of plant and animal species. Coniferous, arctic, and temperate forests have less biodiversity due to harsher or more seasonal conditions.

Answer:

a) Species
