(A) The structure is the cell wall. The cell wall protects the cell from damage. It is also there to make the cell strong, to keep its shape.
(B) Structure Z is a chloroplast. Chloroplasts work to convert light energy of the Sun and turn it in to sugars that can be used by the cells. This process is also called photosynthesis.
(C) Since chloroplasts create sugar for a plant cell, fungi has mitochondria. Fungi uses mitochondria which create ATP (also know as Adenosine Triphosphate) which is energy. Therefore, fungi doesn’t need chloroplasts.
<span>This would be fringing reefs. These reef systems grow near to the coastline as well as around islands and large continents. They are generally separated from the shore via shallow lagoons. They are the most common type of reef system on the planet. They are similar to Barrier reefs which also grow parallel to coastlines, but barrier systems are separated by deeper and much wider lagoons.</span>
A reduction in number of fungi in the food web lead to a decrease in the producers and the other consumers.
- Trophic levels are hierarchies in an ecosystem. The trophic level of an organism is the position in the food chain. A trophic level can be defined as a group of organisms in the same level in a food chain or food web.
- Organisms are organized into various trophic levels. They can either be producers, consumers or decomposers. Decomposers include bacteria and fungi that feed on dead organic matter.
- If fungi were to affect by acid rain that will lead to low yields and then there would be few decomposers in the food web and hence there would be no recycling of nutrients in the food web.
- Fungi help to remove the environment of the dead organic organisms and add nutrients to the soil for use by the primary producers.
