1. Food Web: A food web is a visual representation of the interconnection of organisms within an ecosystem, showing the flow of energy through different trophic levels. It consists of a series of arrows representing the transfer of energy and nutrients from one organism to another.
2. Keystone Species: Keystone species are species that have a disproportionate impact on their ecosystem compared to their abundance. Their removal or decline can lead to significant changes in the structure and function of the entire ecosystem. They usually play a critical role in maintaining biodiversity and regulating the populations of other species.
3. Trophic Pyramid: A trophic pyramid, also known as an ecological pyramid, is a graphical representation of the trophic levels within an ecosystem. It illustrates the distribution of energy, biomass, or number of organisms at each trophic level. The pyramid typically shows producers at the bottom, followed by primary consumers, secondary consumers, and so on, with apex predators at the top.
4. Numbers Pyramid: A numbers pyramid represents the number of organisms at each trophic level in an ecosystem. It shows the decreasing number of individuals as you move up the trophic levels, as energy is lost and organisms become less abundant. Producers tend to have the highest number, followed by decreasing numbers at each higher trophic level.
5. Biomass Pyramid: A biomass pyramid illustrates the total dry mass of all organisms at each trophic level within an ecosystem. It shows the total energy stored in the tissues of organisms in a particular area or ecosystem. Similar to the numbers pyramid, biomass also tends to decrease as you move up the trophic levels, as energy is lost through metabolic processes and not all biomass is consumed by consumers.
