A. Is the correct answer :)
Answer:
When starfish were removed from their environment, the species richness of that area went down. This was because the starfish ate the mussels, and when the starfish were removed, the mussels became abundant and preyed on many of the other species.
This experiment showed that the starfish were a keystone species. A keystone species is a species that has a low biomass but a large impact on the community they are living in.

Answer:</h2>
Differences between coniferous and deciduous forest lie in their names.
<h2>Explanation:</h2>
- One of the biggest differences between forests is in their names.
- Coniferous means 'cone bearing,' and these are trees that have cones, like pine trees.
- Most conifers are considered evergreens, because they never lose their leaves and are 'forever green,' regardless of the season.
- Deciduous means 'falling off'.
- Deciduous trees, on the other hand, lose their leaves each year, which are mainly comprised of trees such as oaks and maple trees.
Result: the difference lies in their name.
