Answer 1

Answer:

1. Habitats are simply those places where aquatic species live. Aquatic habitats can be described in many ways including: ... the shape and nature of the habitat (e.g. pools and riffles, billabongs, reefs), or. the overall ecosystem (e.g. wetlands, floodplains, streams, estuaries, lakes, beaches).
2. Biotic components are living organisms in an ecosystem. A biotic factor is a living organism that affects another organism in its ecosystem. Examples include plants and animals that the organism consumes as food, and animals that consume the organism.
3. Excretion is a general term referring to the separation and throwing off of waste materials or toxic substances from the cells and tissues of a plant or animal. ... The separation, elaboration, and elimination of certain products arising from cellular functions in multicellular organisms is called secretion.
4. Growth is the irreversible increase of an organism's size over a given period. It may also be defined as one of the characteristics of a living thing. In biology, “biological growth” is associated with progressive development. An organism's growth may go on throughout its life, or end when that species is fully mature.
5. In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche.
6. ‘Living’ is something that is alive, something that can grow, move, reproduce, respire and carry out various cellular activities.

7. It is the process by which an organism produces an individual like its own. Reproduction is of two types- sexual and asexual reproduction. Most of the mammals like humans reproduce by sexual reproduction. But when we consider unicellular organisms like bacteria, growth and reproduction become ambiguous as both results from the division of the cell. Thus, reproduction again cannot be considered as a typical character in defining living.

8. Respiration is a chemical reaction that happens in all living cells, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen. Do not confuse respiration with breathing (which is properly called ventilation).

In biology, we can define stimulus as the “detectable change (physical or chemical) in the environment of an organism that results in some functional activity”. For example, sunlight acts as a stimulus for plants that helps them grow or move towards it. ... Thus, rain acts as a stimulus for them.
