Researchers are studying lichens growing on trees in a forest ecosystem. At the beginning of the study, the researchers identified twelve lichen species in the forest. Later, a forest fire happened in the study area. The researchers returned to the area and found only six lichen species. Which inference is best supported from the researchers' observations?
Question 2 options:
Most lichen species are unaffected by forest fire.
The biodiversity in a forest increases after a fire.
Certain lichen species are better adapted to survive forest fires than others.
Forest fires will permanently remove certain species from the ecosystem.
Certain lichen species are better adapted to survive forest fires than others.
An environmental change drastically reduced the population of milkweed plants in an area. The milkweed plants provided the only source of food for a nearby population of monarch butterfly caterpillars. Which statement describes the most likely effect of this environmental change on this population of monarch butterflies?
Question 3 options:
The number of monarch butterflies will decrease because their caterpillars will not have enough food.
The number of monarch butterflies will stay the same because butterflies reproduce so rapidly their populations can withstand most food shortages.
The number of monarch butterflies will stay the same because their caterpillars will begin consuming nectar from different types of flowers.
The number of monarch butterflies will increase because their reproduction rate will increase to ensure some individuals survive.
The number of monarch butterflies will decrease because their caterpillars will not have enough food.
