Which process is represented in the diagram below?

• energy flow

• biological evolution

• cellular communication

• ecological succession

Answer explanation

Changes in an ecosystem over a long period of time are shown in the diagram. These changes will most likely lead to a

• stable ecosystem that can last for many years

• loss of heterotrophs that cannot be recovered

• long-term rise in environmental temperatures

• forest consisting of only producers and decomposers

Answer explanation

This diagram is showing succession, the replacement of one type of community by another until the stable climax community, which remains until it is destroyed by some catastrophe.

Which of the following catastrophic events is likely to lead to secondary succession?

• 
• 
• landslide & volcanic eruption

Answer explanation

A landslide and a tsunami would destroy a lot of the ecosystem but would leave soil behind.

A volcanic eruption would completely erase any living things organisms in an ecosystem and the ecosystem would have to start all over without any soil.

Wolves were reintroduced to Yellowstone National Park in 1995. This keystone species restored the park’s ecosystem. What is the ecological value of a keystone species?

• they protect land and water resources within the ecosystem.

• They decrease the number of unwanted species in an ecosystem.
