Explanation:

Question 47

Renewable energy is energy from sources that are constantly being made (e.g., solar, wind). Non - renewable is finite (e.g., fossil fuels). Kinetic energy is energy of motion. Fossil fuels are non - renewable. So the energy from constantly made sources is renewable energy.

To decrease birth rate, we need to increase factors that reduce fertility. Option a (reducing family planning programs) would likely increase birth rate. Option b (increasing education and employment for women) empowers women to make choices, reducing birth rate. Option c (encouraging early marriage) increases birth rate. Option d (tax breaks for more children) increases birth rate.

Iguanas eat plants, so they are herbivores. Carnivores eat meat, fish are a type of animal, birds have diverse diets. So herbivores are most threatened as iguanas (herbivores) compete with native herbivores for plant resources.

Answer:

a. Renewable energy
