Answer 1

Answer:

1.Ecology is the branch of science that examines the relationships organisms have to each other and to their environment. Scientists who study those relationships are called ecologists. There are many different ways to study ecology. Some types are landscape ecology, population ecology, and behavioral ecology.

The different types of ecology include- molecular ecology, organismal ecology, population ecology, community ecology, global ecology, landscape ecology and ecosystem ecology.

2.The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.

3.Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.

4.A graphical representation in the shape of a pyramid to show the feeding relationship of groups of organisms, and the flow of energy or biomass through the different trophic levels in a given ecosystem
