ecology 1
or meat-eater, is an animal whose food and energy requirements derive solely from animal tissues whether through hunting or scavenging.
carnivore
are largely comprised of carnivores that feed on the primary consumers or herbivores.
secondary consumer
An ecological pyramid is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem
energy pyramid
the process of working together to the same end.
cooperation
an animal that naturally preys on others.
predator
an animal that feeds on carrion, dead plant material, or refuse.
scavenger
An omnivore is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed.
omnivore
is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species
symbiosis
two organisms fighting for the same resource
competition
is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation and parasitoidism.
predation
are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi.
decomposers
an animal that feeds on plants.
herbivore
is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed.
commensalism
both organisms benefits
mutualism
non living organism
abiotic
are animals that consume other animals to obtain nutrition from them. Most importantly, they are at the highest level of the food chain.
tertiary consumer
is a person or a group who intends to order, orders, or uses purchased goods, products, or services primarily for personal, social, family, household and similar needs, not directly related to entrepreneurial or business activities.
A consumer
is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one".
parasitism
an organism that lives in or on an organism of another species (its host) and benefits by deriving nutrients at the other's expense.
parasite
is a linear network of links in a food web starting from producer organisms and ending at an apex predator species, detritivores, or decomposer species. A food chain also shows how organisms are related to each other by the food they eat. Each level of a food chain represents a different trophic level.
A food chain
are herbivores, feeding on plants. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants). There are certain primary consumers that are called specialists because they only eat one type of producers.
Primary consumers
produces energy for a consumer
producer
an animal that is hunted and killed by another for food.
prey
a person who receives or entertains other people as guests.
host
the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Another name for food web is consumer-resource system.
