Consider a field where many plants are specifically pollinated by bees. If there was a sudden increase in the population of a bee predator, such as the dragonfly, we might observe a reduction in the bee population, which would lead to reduced pollination. Select the most likely outcome of this change in the ecosystem. (1 point)

Bees will start to avoid this area because of predation.

Plants that were bee-pollinated will attract new insect pollinators.

Bees will start to avoid this area because of predation.
The most likely outcome of a sudden increase in the population of a bee predator, such as the dragonfly, in a field where many plants are specifically pollinated by bees would be that the plant community will become smaller and less diverse. This is because a reduction in the bee population due to predation would lead to reduced pollination, which can result in lower seed production and reduced plant diversity in the area.

Birds eat berries and seeds, dispersing the seeds in their droppings as they fly.

Birds eat berries and seeds, dispersing the seeds in their droppings as they fly.
The most likely outcome of this change in the ecosystem would be: "The plant community will become smaller and less diverse." This is because the reduction in the bee population, which are important pollinators for these plants, would result in less effective pollination. Consequently, this would lead to a decrease in plant population and a reduction in the diversity of the plant community.
What is the difference between courtship behavior and territorial behavior? (1 point)
Responses
Territorial behavior is the animal of the same kind, but of the opposite sex. Courtship behavior is the production of offspring.

Coevolution can be seen between some plants and animals, like the yucca plant and the yucca moth. The flowers are shaped specifically so that only the tiny moth can pollinate them.
If the yucca moth goes extinct due to climate change or other human-generated factors, what would be the likely outcome for the yucca plant?
(1 point)
Responses
A new animal would evolve or adapt to take over the job of the yucca moth.

The yucca plant would evolve a new way to be pollinated.

Humans would have to engineer a way to pollinate the plant.
Humans would have to engineer a way to pollinate the plant.
The yucca plant would also go extinct.
The most likely outcome for the yucca plant if the yucca moth goes extinct would be that a new animal would evolve or adapt to take over the job of the yucca moth. Coevolution occurs between plants and animals when they have a mutualistic relationship, and in the absence of the yucca moth, it is possible that another species could fill the role of pollinating the yucca plant.

Scientists often rely on data as evidence when looking at an animal's reproductive success. They collect and analyze data on factors such as mating behaviors, offspring survival rates, and reproductive output to understand the reproductive success of individuals or populations. Using data allows scientists to make objective and evidence-based assessments of reproductive success.
A student is analyzing data that compare the change in the total number of wading bird nests in the Everglades to the change in rainfall. Wading birds feed primarily on fish. Fewer nests were observed in dry years than wet years.
What is a reasonable inference about the relationship between wading bird reproductive success and water depth in the Everglades?
Water depth does not affect wading birds’ access to food but does affect wading birds’ reproductive success.
Water depth does not affect wading birds’ access to food but does affect wading birds’ reproductive success.
Water depth likely affects wading birds’ access to food, but this does not affect wading birds’ reproductive success.
Water depth likely affects wading birds’ access to food, but this does not affect wading birds’ reproductive success.
Water depth does not affect wading birds’ access to food and thus does not affect wading birds’ reproductive success.
Water depth does not affect wading birds’ access to food and thus does not affect wading birds’ reproductive success.
Water depth likely affects wading birds’ access to food and thus affects wading birds’ reproductive success.
