Answer: d)All of the above
Explanation: Competitive effect is defined as the interaction created between species or organism , which usually results in negative situation. There are certain condition for the competition such as supply of any resource in limited quantity, etc.So competition is also invoked by the density of the species present and in order to exist in an ecosystem and thus there is the high chances of the overlapping of species as well.
Therefore,option(d) is the correct option.
Answer:then Nathan is rich
Explanation:
A bioindicator is a living organism that gives us an idea of the health of an ecosystem. Some organisms are very sensitive to pollution in their environment, so if pollutants are present, the organism may change its morphologyphysiology or behaviour, or it could even die. Hope that helped!
<h3>Global travel and spread of certain species</h3>
Explanation:
Many pathogenic species of bacteria, virus, and other microbes are more prevalent in developing or tropical countries rather than in developed countries.
When an individual’s immune system is weak they become more susceptible to get infected and become carriers of that particular species.
The species grows, develops, and multiplies in the host’s body and when the traveler travels to his/her home country or any other place he/she can transmit the disease to others and again the species grows in numbers. Higher the rate of spread of infection higher is the increase in species.
<span>Sedimentation - uses solutions of lower specific gravity than the organisms, which concentrated in the sediment. This technique is recommended for general diagnostic laboratories because it is easy to perform and less prone to technical errors.
Flotation - this technique uses solutions of higher specific gravity than the parasitic organisms so the organisms float and the debris sinks producing a cleaner material while the disadvantage is that walls of cysts and eggs collapse that may blocking its identification.<span>
