Think you an expert of Ecology? Ecology is a division of life science that deals with examining organisms and their relationships with other organisms and their environment. Natural Science is one of the most exciting and complex forms of science: an ecologist studies living things and their habitats. Ecology shapes the distribution and abundance in the environment. If you are looking for a way to study for the ecology test, this incredible quiz can help.
The carnivores can provide more food for the Eskimos than the herbivores can.
Polar bears can provide more food for Eskimos than seals can.
Polar bear meat probably contains the highest concentrations of fat-soluble toxins.
The total energy content of the seaweeds is lower than that of the seals.
) Seals are more numerous than fish.

Nitrogen-fixation involves the conversion of ammonia to nitrates.
Nitrogen-fixation may be accomplished by the action of lightning.
Nitrogen gas reacts with oxygen in the air to produce nitrates.
Plants supply nitrogen-fixing bacteria with the sugar they need to make the nitrates.
Nitrogen-fixation may be accomplished by bacteria that grow on the roots of legumes.
