Answer:cacti
Explanation:
In an ecosystem,the ultimate source of energy is the sun. Plants take up this energy from the sun to produce food. Animals eats up plants and when they die ,they decompose. This continuing process leads to the transfer of energy from one trophic level to another in the ecosystem.
Plants ,algae and some bacteria are the primary producers in the ecosystem.they are able to make their own food and support the entire living system. They extract inorganic nutrients and energy from the environment, in order to make their food. Animals(herbivores) eats up the plants and other animals(carnivores) eat up such animals. This situation sets up a chain of flow of energy from the producer to the consumer and back to the environment.
The added energy is need to break hydrogen bonds between water
First we must describe how immunity works. Immunity works by recognition of the antigen by macrophages or dendritic cells (antigen presenting cells) then presenting it to T cells and T cells will work to destroy the organisms with the specific antigen. B cells can also recognize antigens then secrete antibodies to combat organisms with the specific antigen. In the case of flu, or influenza, the genetic material of the virus mutates so often that the antibodies produced by the body against a certain strain of influenza will not work after some time because of the mutation of the virus.
