Question

during a period of secondary succession, a scientist observes a new population of flowers appearing in the environment. these flowers are able to survive in harsh conditions and are among the first species to colonize the area. what type of species best describes this flower population? keystone species pioneer species climax species

Explanation:

• Keystone species: These species have a disproportionately large effect on their environment relative to their abundance. They play a crucial role in maintaining the structure of an ecological community. For example, sea otters are keystone species as they control sea urchin populations, which in turn affects kelp forest ecosystems. However, the description in the question does not mention such a role in maintaining community structure.
• Pioneer species: These are the first species to colonize barren environments or areas undergoing secondary succession. They are often hardy and can survive in harsh conditions. In secondary succession (where there is already some soil and remnants of a previous ecosystem), pioneer species like certain flowers can quickly establish themselves. This matches the description of the flower population in the question.
• Climax species: These are the species that remain in an area when a stable community (climax community) has been reached. They are well - adapted to the local conditions but are not the first to colonize an area during succession.

Answer:

pioneer species
