Answer:
Decomposers
Explanation:
The diagram in this question illustrates a food web, which is a series of interlinked food chains in an ecosystem. In a food chain as depicted in the image, the arrows point to the organism that feeds on another organism. For example, an arrow is pointing from Idaho fescue to an Elk meaning that the elk will feed on that plant.
Different trophic levels constituting organisms exists in the food web including; producers (plants), primary consumers, secondary consumers, tertiary consumers etc. However, as observed in the image, a general arrow carrying along all the organism is pointing towards the organism in the question mark. This organism is called DECOMPOSER.
A decomposer, usually a microorganism, is an organism that breaks down dead organisms and returns the nutrient to the soil for recycling. All organisms in the food web will eventually die and when they do, they'll be decomposed by a decomposer. This is why the arrow pointing towards the decomposers include all organisms.
When Went placed the agar block on one side of the decapitated shoot, the shoot curved away from the agar as it grew. This demonstrated that some kind of hormonal signal had diffused into the agar from the coleoptile tips. ... Went's experiment represented the first time that anyone had isolated a hormone from plants.
Answer:
<h3>The micro-organisms which convert the dead plants and animals to humus are known as decomposers.</h3>
<h3> Examples: Fungi and Bacteria. Decomposers recycle and convert the dead matter into humus which mixes with forest soil and provides necessary nutrients to plants.</h3>
I believe it’s the study of agriculture (c)
