Oftentimes, scavenger communities differ in consistency due to carcass size and carcass types, as well as by seasonal effects as consequence of differing invertebrate and microbial activity. [4] Competition for carrion results in the inclusion or exclusion of certain scavengers from access to carrion, shaping the scavenger community.
Consumer–resource interactions are the core motif of ecological food chains or food webs, [1] and are an umbrella term for a variety of more specialized types of biological species interactions including prey-predator (see predation), host-parasite (see parasitism), plant-herbivore and victim-exploiter systems.

A strawberry aggregate accessory fruit damaged by a mouse eating the seeds ().. Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source, [1] in many cases leaving the seeds damaged and not viable.

A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
Plant tissues are made up of resilient molecules (e.g. cellulose, lignin, xylan) that decay at a much lower rate than other organic molecules. The activity of detritivores is the reason why there is not an accumulation of plant litter in nature. [2] [3] Two Adonis blue butterflies lap at a small lump of feces lying on a rock.
The evolution of various structural and morphological adaptations of present-day palynivores has also been thought to have co-evolved with pollen grains. [7] The abundance and diversity of seed-bearing plant fossils identified from the Late Pennsylvanian suggest greater palynivore evolution and adaptations to the evolving plant fauna.
