Competition is a relationship between organisms that strive for the same resources in the same place. Intraspecific competition occurs between members of the same species. For example, two male birds of the same species might compete for mates in the same area.

Interspecific competition occurs when members of more than one species compete for the same resource. Woodpeckers and squirrels often compete for nesting rights in the same holes and spaces in trees, while the lions and cheetahs of the African savanna compete for the same antelope and gazelle prey.

Intraspecific competition occurs among individual members of the same population, for example, when sprouts grow from seeds scattered closely together on the ground. Some seedlings will be able to grow faster than others and will inhibit the growth of less vigorous seedlings by overshadowing or overcrowding them.

The interaction among organisms within or between overlapping niches can be characterized into five types of relationships: competition, predation, commensalism, mutualism and parasitism.

The populations of all the different species that live together in an area make up an ecological community. Interactions between two or more species are called interspecific interactions. …

There are three basic types of symbiosis: mutualism, commensalism, and parasitism.

A tapeworm lives inside the intestines of a pig, robbing the pig of nutrients it needs.

5 Types of Parasitism. Parasites that live inside the body of the host are called endoparasites and those that live on the outside are called ectoparasites. An epiparasite on the other hand is a parasite that feeds on another parasite.

Examples of parasites include:

• stomach and gut worms (threadworm, hookworm)
• skin mites (scabies)
• hair and body lice (head lice and crab lice)
• protozoa (Giardia)

So, the correct answer is ‘Entamoeba histolytica’

: obtaining food by absorbing dissolved organic material especially : obtaining nourishment from the products of organic breakdown and decay saprophytic fungi.

Saprophytes are organisms that can’t make their own food. In order to survive, they feed on dead and decaying matter. Fungi and a few species of bacteria are saprophytes. Examples saprophyte plants include: Indian pipe.

Organisms who live and feed on dead organic materials and obtain nutrition for their growth are known as saprophytes. Example – Mucor, yeast. Saprophytes are mostly fungus and/or bacteria. Saprophytes decompose dead plants and animals and convert complex molecules into simpler molecules.

Complete answer: Saprophytes are the living organisms that get their energy from dead and decaying organic matter which may be decaying plants or animals. Saprophytes are heterotrophs and are consumers in the food chain.

Yeast and Mushroom are some of the saprophytic organisms. Saprophytes feed on dead and decaying organisms only and not in living organisms. They secrete digestive juices on the matter they live and convert it into a solution and then absorb it. Organisms which use saprophytic mode of nutrition are called saprophytes.

Some examples of saprophytic fungi include molds, mushrooms, yeast, penicillium, and mucor etc. Bacteria: Some bacteria survive by breaking down various organic matter including those of dead and decaying animals. As such, they are not saprophytes.

Saprophytes. Those non-green plants which obtain their food (or nutrition) from dead and decaying organic matter are called saprophytes. This mode of nutrition in which plants take in nutrients from dead and decaying organic matter is called saprophytic nutrition.
