What is autoroph?

Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis using inorganic compounds. They are able to convert sunlight or other forms of energy into organic molecules that can be used as nutrients. Plants and some bacteria are examples of autotrophs.


What does a biomass pyramid measure?

Biomass. Pyramids of biomass and number are scientific models to represent all the things eaten in a foodchain. Pyramids of number are flawed as a great many insects may feed on a tree, for example, producing a narrow base to the pyramid. Pyramids of biomass are a better model as they show the dry mass of each part of the food chain and give a better indication of the energy passed between trophic layers. Biomass pyramids show the abundance of organisms at each trophic level.

What important role of mosquitoes in ecosystems can be shown in ecological pyramids?

Balance through parasitism, pollination and prey are the important roles that mosquitoes hold in ecosystems and that ecological pyramids recognize at the next-to-the-lowest level occupied by primary consumers. Mosquito larvae eat such representatives of the lowest production level as algae and fungi whereas adults prey upon such liquids as body fluids and plant nectars. In the process, mosquitoes transfer pollen from one part of a plant to another or from plant to plant in the course of nectaring and transmit viruses in the course of sipping such fluids as human blood.
