Contractile means the ability of an organism to<u><em> withhold, reduce in size or shrink. </em></u>

A contractile vacuole will help this organism better survive in its moist environment by <u><em>preventing or stopping the cell from absorbing too much water from its moist environment.</em></u>

- A contractile vacuole is an <em>organelle</em> that can be found in organisms that are said to be <u><em>single-celled (Unicellular organisms).</em></u>
- One of the primary functions of a contractile vacuole is to absorb <u><em>excess water</em></u> from the protoplasm in the unicellular organism and release this water to the surrounding environment.
- A contractile vacuole can be called the excretory organ of unicellular organisms. This is because it is involved in <u><em>osmoregulation.</em></u>

A reproductive strategy presents an approach of a type of an organism to reproduction and of taking care of it's offspring.
Generaly speaking, there are two main reproductive strategies, K and R reproductive strategies.
The organisms that apply the R strategy produce a great number of small, independent offspring and when the offspring is born or hatched it's left to
try to survive on its own. This strategy is used by bacteria, many invertebrates, and reptiles.
On the other hand, the K strategy organisms produce a small number of offspring that they care of for a significant amount of time after they are born. This strategy is used mostly by mammals and birds.
Answer:
Explanation:
(a) interspecific competition: It is a kind of competition that occurs between the individuals that belong to different species competing for the same resource in an ecosystem. For example, lion and tiger populations thriving for the same type of prey that is deer population.
(b) intraspecific competition: Interspecific competition occurs between the members of the same population competing for limited resources. For example, trees of the same species competing for the sunlight and soil nutrients.
(c) predation: It is an ecological interaction that occurs between the superior or inferior species. One animal kills other animal to obtain it as a source of food. For example a tiger kills a deer to obtain it as food.
(d) territoriality: It is a quality of a species or a population of species to obtain the geographical area to an extent or limit where no other species or population can intrude. For example, lion shows the territory behavior to protect their children from predators.
(e) symbiosis: It is a type of biological interaction in which two species lives in association with each other. This interaction can be mutualistic, parasitic or commensalistic. For example, a lice sucking blood from animal is an example of parasitic symbiosis.
