The elimination of a predator has no negative impacts on that predator’s prey species.a. True
b. False

Answers

Answer 1
Answer:

Answer:

The given statement is False.

Predator-prey relationship is a biological relationship in which one organism kills and eat the other organism in an ecosystem. The organism who killed is termed as predator and the organism who is killed is termed as prey.

It helps in controlling the population size of prey, helps in slowing down the spread of the disease, and in the establishment of a healthier prey population by removing or killing the injured or sick animals.

Complete removal of the predators will lead to the overpopulation of their prey which is generally herbivores. The over-populated herds will eat more and more grass which will ultimately lead to the shortage of food.

So, the herds will starve to death.

Hence, we can conclude that the removal of predator has negative impacts on that predator’s prey species.

How many calories of energy will 20 grams of carbohydrates provide if 1 gram provides 4 calories?A. 80 calories
B. 100 calories
C. 200 calories
D. 240 calories

Answers

80 calories of energy will 20 grams of carbohydrates provide if 1 gram provides 4 calories. So, the correct option is (A).

What are Calories?

Calorie is defined as the amount of energy the body releases when it breaks down i.e. digests and absorbs food. The more calories a food contains the more energy it can provide to the body. When we eat more calories than we need, our body stores the extra calories as body fat.

Women need 1,600–2,400 daily calories to maintain their weight while the men need 2,000–3,000 calories. Eating fewer can lead to weight loss. By reducing the number of calories we eat per day can be an effective weight loss method.

Different nutrients provide different amount of calories, for example,

  • one gram carbohydrate provide 4 calories energy
  • one gram protein provide 4 calories energy
  • one gram fat provide 9 calories energy

Thus, 80 calories of energy will 20 grams of carbohydrates provide if 1 gram provides 4 calories. So, the correct option is (A).
