Answer:
B
Explanation:
A cannot be true as photosynthesis requires carbon dioxide and water and uses light energy to break bonds and form oxygen and glucose
C cannot be true as chloroplasts contain chlorophyll which gives the cell its green colour by not absorbing green wavelengths of white light
D is not right as I do not believe photosynthesis is a basic function
Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.
Answer:
O True
Explanation:
Ecosystem engineers are able to modify the surrounding environment, either by creating new habitats or modifying/destroying existing ones to adjust them to their needs. These species can significantly alter their environments, having a large impact on the species richness as well as modifying the availability of abiotic factors (e.g., water, space, etc) of a particular area. In certain environments, ecosystem engineers can even act as keystone species. Some examples of ecosystem engineers include, among others, beavers, woodpeckers, corals, etc.
Without enough light, a plant cannot photosynthesize very quickly, even if there is plenty of water and carbon dioxide.
