Soils, water, and the atmosphere are major components of the abiotic (nonliving) environment. Describe how green plants affect the abiotic environment in ways that are advantageous to humans.

Question

Accepted Answer

Welcome back everyone. Here's the next question. Which of the following is the main rule of green plants in the ecosystem. When we look over four answer choices, we see that we have choices about whether they're consumers or producers and then whether in terrestrial or aquatic ecosystems. When we think about green plants, we recall that they are producers, producers being things that create new organic molecules from inorganic substrates. So in the case of green plants obviously we have photosynthesis being that process using the energy of sunlight and carbon dioxide from the air to create new organic molecules so we know they're producers. So let's eliminate any answer choices which have consumers as their role. So Choice A. Says they are important consumers and terrestrial ecosystems. So we can eliminate that. And Choice C. Says there are primary consumers and terrestrial ecosystems so we can eliminate that. So then let's look at our other remaining choices. Choice B says they are the only producers in aquatic ecosystems. Well, aquatic ecosystems, there are green plants, sea grasses, there are that are producers in aquatic ecosystems. However they are not by any means the only producers or even the major producers um aquatic ecosystems have algae and phytoplankton and bacteria that all also can photosynthesize. Um And you also have the very deep sea creatures that can produce energy using other inorganic compounds. So they are definitely not the only producers in aquatic ecosystems. So Choice B. Is not our answer. So we're left with choice D. They are major producers of terrestrial ecosystems and this is correct. They are the major producers of terrestrial ecosystems. So Choice D. Is our answer. We'll see you in the next video.
