As the cell size increases, the ratio of surface area to volume DECREASES.
The surface area to volume ratio refers to the area per unit volume of a cell. As a cell increase in size, the surface area and the volume of the cell also increase but at an unequal rate, a point will be reached where the ratio of the surface area to volume will be so low that the diffusion becomes very inefficient, at this point, the cell has to divide in order to increase its surface area to volume ratio and to increase its diffusion rate.
Answer:
When all of the populations live together in the same area, it is called:
A community
Why? Because a community occurs when multiple people are together, and the prefix com means "together".

Answer: Option A) The seals would decrease in number and the phytoplankton would increase in number
Explanation:
The food web can be illustrated as follows: Seal --> Krill --> Phytoplankton
Where phytoplankton is the producer of food, krill is the primary consumer while seal is the secondary consumer.
So, reducing the krill population would immediately cause food shortage for seals, and lessen consumption of phytoplanktons.
Thus, the seals would decrease in number due to starvation and death, while the phytoplankton would increase in number
A catalyst increases the rate of reaction by providing a metabolic pathway that requires less energy. There for they work by decreasing the activation energy of a reaction.
