The biotic components of a community can cause both primary and secondary succession. Primary succession occurs on bare rock or newly formed land, while secondary succession occurs in areas that were previously inhabited but then disturbed. Both types of succession involve the gradual replacement of species over time in response to environmental changes.
Population: all of the induvisuals of one species that live in the same area at the same time Community: the populations of different species that interact in some way
There are various branches of ecology, including population ecology (study of groups of individuals of the same species), community ecology (study of interactions between different species in a community), ecosystem ecology (study of energy and nutrient flows within an ecosystem), and landscape ecology (study of patterns and processes across multiple ecosystems). Each branch focuses on different levels of organization within the environment.
A pioneer plant is one which will be the species first to inhabit a new, barren environment. (eg moss). A climax plant is one which will dominate a mature fertile environment. (eg Oak trees).
Fossil evidence: Fossils provide a record of ancient life forms, showing gradual changes over time that support the idea of evolution. Comparative anatomy: Similarities in bone structure across different species suggest a common ancestry and gradual modifications over generations. Embryology: Similarities in early stages of development among different species provide evidence for a shared evolutionary history. Molecular biology: Genetic similarities and differences between species can help trace evolutionary relationships and patterns of descent. Biogeography: Distribution of species around the world can be explained by evolution, as related species are often found in geographically close areas.

succession
A gradual change in the kinds of organisms living in an ecosystem, typically in response to environmental factors, is known as ecological succession. This process involves a series of stages that ultimately lead to a stable community of plants and animals in the ecosystem.

Succession is the gradual change in living communities that occurs following a disturbance. It involves a sequence of predictable changes in the types of species that inhabit the area, eventually leading to a stable, mature ecosystem.
Ecological succession is the gradual change in the make-up of a biological community over time. In the process of ecological succession, organisms that are present at one stage change the environment in some way. This change make it possible for other species to move in, because the new conditions are more suited to their needs.
The three main types of species interactions in a community are competition, predation, and mutualism. Competition occurs when species compete for limited resources, predation involves one species feeding on another, and mutualism is a symbiotic relationship where both species benefit.
