b. scavengers
c. carnivores
d. decomposers

Decomposer goes in the box five of the food web.

Further Explanation:

The first step of the food chain starts with energy which is absorbed by the plants during the process called photosynthesis. Photosynthesis is the process by which plants make their own food by using sunlight, carbon dioxide and other nutrients. The food formed by plants is consumed by the primary consumers. This cycle is ended by the decomposer. They act as a clean-up crew that means they help in consuming the dead plants, animals and carcasses.

Decomposers play a crucial role in the food chain. The plants require energy of the sunlight and nutrients present in the soil to produce food and decomposers helps in returning these nutrient back into the soil. The living organisms at the start of the cycle depend on the processes at the end of the chain. The elements like carbon, phosphorus and nitrogen that enters the food chain through plants is essential for animals as well. So, these elements enter the animals or human body through eating plants and other animals and the decomposer particularly bacteria and fungi return these elements to the soil through decomposition and mineralization process.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
