2 food chains in ecosystem Biology Diagrams The flightless dung beetle occupies an ecological niche: exploiting animal droppings as a food source.. In ecology, a niche is the match of a species to a specific environmental condition. [1] [2] It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens An ecological niche is a term used by ecologists to describe the role a species plays in an ecosystem. The niche is affected by biotic and abiotic factors. Ecological niches are affected by interspecies competition. This leads to competitive exclusion, overlapping niches and resource partitioning. the chain of islands known as the Channel Food chains reveal the relationships between organisms, showing how each organism plays a role in maintaining ecological balance. By studying food chains, ecologists better understand ecosystem dynamics, including the flow of energy, population control, and the impact of human activities on natural habitats.
A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. These organisms exert major influence over a community's structure by ecological roles or niches. Keystone species are defined Trophic levels and ecological niches are fundamental concepts in ecology that help explain how organisms interact within their environments. The trophic level defines an organism's position in the food pyramid, which typically consists of primary producers at the base (photosynthetic plants), followed by primary consumers (herbivores), secondary consumers (omnivores), tertiary consumers Importance of Ecological Niche. It permits the coexistence of several species, usually without intense competition and under scarce shared resources. It facilitates species to be aware of their position in the food chain and ecology. The number of niches in an ecosystem defines the number of species present. Thus, they define the variety of the

Each niche contributes uniquely to the web of life, affecting food chains and habitat stability. Exploring aspects such as keystone species, resource partitioning, and trophic level niches enhances our understanding of ecosystem function and adaptation. This exploration reveals the balance that sustains life on Earth. Keystone Species Ecological Niche: A niche is the Food Chains and Webs: These represent the energy flow in an ecosystem, from producers to the top predators. Ecological succession is the gradual process by which communities of plant and animal species in an ecosystem are replaced over time, leading to a relatively stable climax community. Ecologists have documented many characteristics of natural systems that foster ecosystem persistence, and it might be deduced that such strategies are essential for counteracting the negative effect of complexity on local stability that was suggested by R.M. May in his influential work of the 1970s. โฆ
