51Ecosystem ecology — Figure 1. A riparian forest in the White Mountains, New Hampshire (USA). Ecosystem ecology is the integrated study of biotic and abiotic components of ecosystems and their interactions within an ecosystem framework. This science examines how… …
52Optimal foraging theory — Ants dismember a larger insect. Optimal foraging theory predicts these insects will forage in such a way as to maximize their colony s energy intake per unit time. Optimal foraging theory is an idea in ecology based on the study of foraging… …
53Non-trophic networks — Any action or influence that species have on each other is considered a biological interaction. These interactions between species can be considered in several ways. One such way is to depict interactions in the form of a network, which… …
54Microbial mat — A microbial mat is a multi layered sheet of micro organisms, mainly bacteria and archaea. Microbial mats grow at interfaces between different types of material, mostly on submerged or moist surfaces but a few survive in deserts.[1] They colonize… …
55Dominance (ecology) — For other uses, see Dominance. Rhizophoraceae dominate tropical tidal swamps Ecological dominance is the degree to which a species is more numerous than its competitors in an ecological community, or makes up more of the biomass. Most ecological… …
56Trophic level — First trophic level The plants in this image, and the algae and phytoplankton in the lake, are primary producers. They take nutrients from the soil or the water, and manufacture their own food by photosynthesis, using energy from the sun. The… …
57Environmental niche modelling — Environmental niche modelling, alternatively known as species distribution modelling, (ecological) niche modelling, and climate envelope modelling refers to the process of using computer algorithms to predict the distribution of species in… …
58Carnivore — Carnivorism redirects here. For the diet, see No carbohydrate diet. For other uses, see Carnivore (disambiguation). Lions are voracious carnivores; they require up to seven kilograms (15 lbs) of meat per day. A major component of their diet is… …
59Photosynthesis — Composite image showing the global distribution of photosynthesis, including both oceanic phytoplankton and vegetation …
60Bioaccumulation — refers to the accumulation of substances, such as pesticides, or other organic chemicals in an organism. [1] Bioaccumulation occurs when an organism absorbs a toxic substance at a rate greater than that at which the substance is lost. Thus, the… …
