Which of the following is true about island biodiversity?

• Small islands are more likely to have more immigrated species

• Small islands have higher biodiversity than large islands

• Small islands have more resources and as a result may have more species

• Small islands have fewer resources and as a result may have fewer species

Which of these ecosystems would be most likely to recover?

Yucca flowers are pollinated by yucca moths. The moths lay their eggs  in the flowers where  the larvae hatch and eat some of the developing seeds. Both species benefit.

What is happening at the 'A' on the graph?

• the population overshoots above the carrying capacity

• the population stops growing

• growth begins to slow down due to limited resources

• growth is speeding up due to an abundance of resources
