This top level of the ecological pyramid was fully occupied and functioning.

Ecological pyramids place the primary producers at the base.

When an ecosystem is healthy, this graph produces a standard ecological pyramid.

It was like an ecological pyramid planted in the wilderness except for this gnome-change.

Ecological pyramid or trophic pyramid, a representation of a food chain.

Their importance is great, for they form the peak of the ecological pyramid and their prey comprises many of the antelopes already described.

An ecological pyramid of productivity is often more useful, showing the production or turnover of biomass at each trophic level.

'The ecological pyramid,' Cal agreed.

Graphic representations of the biomass or productivity at each tropic level are called ecological pyramids or trophic pyramids.

Wolves dominated those landscapes throughout most of history, occupying the summit of the ecological pyramid until recently, when they were shot, trapped and poisoned nearly out of existence.

Among marine animals, pesticide concentrations are higher in carnivorous fishes, and even more so in the fish-eating birds and mammals at the top of the ecological pyramid.

Ecological pyramids are graphical representations, along the lines of the diagram at the right, which show how biomass or productivity changes at each trophic level in an ecosystem.

Because we Yilanè are at the summit of the ecological pyramid we automatically assume-I automatically assume-that we are alone there, something special and singular.

An ecological pyramid (also trophic pyramid or energy pyramid) is a graphical representation designed to show the biomass or biomass productivity at each trophic level in a given ecosystem.

An ecological pyramid of biomass shows the relationship between biomass and trophic level by quantifying the amount of biomass present at each trophic level of an ecological community at a particular moment in time.

Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat herbivores, then carnivores that eat those carnivores, and so on).

Ecological pyramid or trophic pyramid, a representation of a food chain.

Keystone species have lower levels of biomass in the trophic pyramid relative to the importance of their role.

The elimination of wolves from Yellowstone National Park had profound impacts on the trophic pyramid.

Graphic representations of the biomass or productivity at each tropic level are called ecological pyramids or trophic pyramids.

Due to bioaccumulation and biomagnification, the species at the top of the trophic pyramid are most vulnerable to dioxin-like compounds.

Examples are Vogel and Ewel who published 'An Electrical Analog of a Trophic Pyramid' (1972, Chpt 11, pp.

This, coupled with extremely low numbers of vampire even at peak population levels (existing as they did at the tip of the trophic pyramid) explains their virtual absence from the fossil record.

Thus, organisms higher in the trophic pyramid have accumulated higher levels of N ( and higher δN values) relative to their prey and others before them in the food web.

An ecological pyramid (also trophic pyramid or energy pyramid) is a graphical representation designed to show the biomass or biomass productivity at each trophic level in a given ecosystem.

Organisms which feed on autotrophs, the producers of the trophic pyramid, are known as herbivores or primary consumers; those that feed on heterotrophs such as animals are known as secondary consumers.

Biodiversity within ecosystems can be organized into trophic pyramids, in which the vertical dimension represents feeding relations that become further removed from the base of the food chain up toward top predators, and the horizontal dimension represents the abundance or biomass at each level.

There is access to tools such as trophic pyramids, identification keys, biogeographical modelling and fishery statistics and there are direct species level links to information in other databases such as LarvalBase, GenBank, the IUCN Red List and the Catalog of Fishes.

Human being is also at the top of the trophic pyramid, but due to a multitude of food sources as compared with seals and eagles feeding almost exclusively on fish, human concentrations are much less, 10-100 pg/g, compared with 9000 to 340,000 pg/g (TEQ in lipid) in eagles.

As before, she was shown in an energy pyramid and emitted energy bolts from her hands.

On some oceanic islands, terrestrial crabs occupy the top of the energy pyramid.

This is called an energy pyramid.

"Have they found cosmic energy pyramids on Mars?

An energy pyramid is a way of showing how energy flows through an ecosystem specifically on a certain food chain (predators and their prey).

In 2004 in the Netherlands Ruben developed a construction called "The Energy Pyramid".

Energy pyramids, however, will always have an upright pyramid shape if all sources of food energy are included and this is dictated by the second law of thermodynamics.

An ecological pyramid (also trophic pyramid or energy pyramid) is a graphical representation designed to show the biomass or biomass productivity at each trophic level in a given ecosystem.

The energy transferred between levels can also be thought of as approximating to a transfer in biomass, so energy pyramids can also be viewed as biomass pyramids, picturing the amount of biomass that results at higher levels from biomass consumed at lower levels.
