Which of the following statements is TRUE about the graph?

• The rabbit’s population is increasing from August 1st to September 1st.

• The carrying capacity of the rabbit is 65, and it is constant from the first month up to the last month.

• The carrying capacity of the rabbit is 65, and there is a slow phase of population growth from June 1st to August 1st.

• The rabbit’s carrying capacity is 65. The rabbit’s population stops growing,

  indicating that the area can only accommodate and support 65 rabbits.

A biologist is studying a natural population of mice and observes that in one area the proportion of darker-colored mice is greater than the proportion of lighter colored mice. In another area, the opposite is true. He finds that only the area with more dark mice has predators. Therefore, you hypothesize that darker mice are favored in areas with predators, perhaps because they are more difficult to If your hypothesis is true, what would you expect to happen in the few generations after predators are introduced to an area with a population of mice that previously did not have predators?

• The proportion of darker-colored mice will increase.

• The proportion of darker-colored mice will decrease.

• The proportion of darker-colored mice will not change.

• The predators will evolve to be able to better see the darker mice.

Organisms are part of it and may be economically and ecologically valuable. Their products are sources of food, medicine, clothing, shelter, and energy. These organisms are also important in maintaining balance in the ecosystem, as they are performing their specific roles. What is the term that describes the variation of living things in a specific area?

• Biodiversity

• Ecosystem

• Habitat

• Population

Jade tried to breed carabaos in a huge and isolated cabin. After a few generations, he observed that carabaos were getting aggressive toward each other. The young are less healthy, and more calves die. What do you think will happen to the population of carabaos?

• The population will increase.

• The population will decrease.

• The population is not affected.

• The population will remain the same.

The number of rats in the rice field is continuously growing at an exponential rate.

Which of the following statements supports the exponential rate of the rats?

• Most of the rats carry contagious diseases.

• Many female rats developed numerous babies.

• Most of the male rats are fighting, which causes them to die.
