Answer:
Competition refers to the phenomena in ecology, in which two or more species acquiring the same ecological niche ( type of habitat, food sources and others) compete with each other in order to derive resources, survive and increase in number.
Indirect competition is a competition in which one species/ organism depletes the resources in the ecosystem, making it unavailable for the other species/ organism. Such resources includes nests sites, food items, water and minerals in the soil. In this type of competition species/organisms does not directly interact and fight for resources with each other. In intraspecific indirect competition, the competing organisms are of the same species. Example: The bears that catches fishes in the river at different locations, will make fishes unavailable for other members of the same species. There, will be no direct competition among the bears of the same species for food. In interspecific indirect competition, the competing organisms belong to different species. Example: The diurnal cheetahs and nocturnal leopards using the same waterhole in the savanna grassland.

Like proteins, Ribonucleic acid is another kind of organic molecule that also acts as a catalyst for chemical reactions. Asides acting a catalyst for chemical reactions, proteins have a wide variety of functions that they perform in in living cells.
Answer: Starch, Cellulose, inulin etc
Explanation:
Several units of glucose (monosaccharides) are linked to form polysaccharides. These polysaccharides are found in living things
For example:
In plants, starch serve as a stored form of energy, while cellulose, an indigestible material provide strength to plants
Also, starch consists of monosaccharides i.e glucose units with an alpha α-1, 4-glycosidic bond; while cellulose has the same glucose units, but linked by beta β-1, 4-glycosidic bonds
