Question

b. draw a food web that includes at least two plants, and four animals that relates to this biome.
c. identify one keystone species found in that biome. describe what makes that organism critical to the survival of that ecosystem.
d. anthropocene impacts: briefly describe one negative human impact affecting this biome.

Explanation:

b. A food - web is a graphical representation of feeding relationships in an ecosystem. For example, in a grassland biome, plants like grass and wildflowers can be part of the food - web. Animals such as rabbits, grasshoppers, foxes, and hawks can also be included. Arrows in the food - web indicate the direction of energy flow from one organism to another.
c. In a kelp forest biome, sea otters can be a keystone species. They control the population of sea urchins, which if left unchecked, would over - graze on kelp, destroying the habitat for many other species.
d. In a tropical rainforest biome, deforestation is a major negative human impact. Humans cut down trees for agriculture, logging, and urbanization, which reduces habitat for countless species, disrupts the water cycle, and contributes to climate change.

Answer:

b. (A hand - drawn food web with appropriate plants and animals and arrows showing energy flow should be created. For example, Grass → Rabbit → Fox; Wildflower → Grasshopper → Hawk)
c. Sea otters in a kelp forest biome. They control sea urchin populations to protect kelp.
d. Deforestation in a tropical rainforest biome reduces habitat and disrupts ecological processes.
