Answer:
light is required to provide energy for photosynthesis
Explanation:
For photosynthesis to take place, it requires the presence of light and chlorophyll. The process has two stages; light and dark stage.
In the light stage, chlorophyll molecules absorb light energy which is used to split water molecules into oxygen and hydrogen atoms. The process is called photolysis.
water→ hydrogen atoms + oxygen.
The hydrogen atoms produced enter the dark stage while oxygen is released in the atmosphere. In the dark stage, carbon dioxide combines with the hydrogen atoms to form simple sugar such as glucose.
If I'm not mistaken, it leaves through the osculum which is a cavity located on the upper part of a sponge.
Sponges feed through a process called filtration, which means that they filter the water in search of nutrients. And after they collect everything they need from the water, they need to let it out somehow; through the osculum.

Answer:
The correct option is D) The age-structure diagram would be column-shaped with all age classes approximately equal.
Explanation:
A zero population growth refers to a condition when the birth rate equals to the death rate. Social workers tends to find methods to attain zero population growth as such conditions provide economic stability. As the birth rate and the death rate will be equal hence the age structure diagram of such a population can be seen to be column shaped as they all will be equal.
