Question

Gracilaria verrucosa is a type of algae that can live in a salt marsh, which is sometimes covered by ocean water, or in a subtidal habitat, which is almost always covered by ocean water. It was discovered that the G. verrucosa living in the subtidal habitat had a photosynthetic rate 5 to 10 times higher than the same species living in the salt marsh habitat. Which statement best explains this difference?

Answer 1

Complete question:

Graciela verruca is a type of algae that can live in a salt marsh, which is sometimes covered by ocean water, or in a sub-tidal habitat, which is almost always covered by ocean water. It was discovered that the G. verruca living in the sub-tidal habitat had a photosynthetic rate 5 to 10 times higher than the same species living in the salt marsh habitat. Which statement best explains this difference?

1. there is more oxygen available in the sub-tidal habitat,

2.There is more carbon dioxide available in the salt marsh habitat

3. The G. Verruca in the sub-tidal habitat contains more chlorophyll

4. The G. Verruca in the salt marsh habitat contains more mitochondria

Answer:

The G verruca in the salt marsh habitat contains more mitochondria.

Step-by-step explanation:

Salt marsh or salt marsh, also classified as coastal salt marsh or tidal marsh, is a marine habitat in the upper marine intertidal region between land and free salt or brackish waters, and is periodically filled by tides.

While it is called a freshwater marsh, this type of marsh is influenced by ocean tides.

Salt marsh plants have had to tolerate all flooding and water.
