In a swamp a bird and a turtle feed on the same kind of fish. This will most likely result in Competition is an relations between organisms or species in which both need a resource that is in limited pool.
<h3>What is competition in an ecosystem?</h3>
Competition will happen between organisms in an ecosystem when their niches overlay , they both try to utilize the exact resource and the resource is in lack of supply.
Fuana contend for chow, water and area to live. flora contend for light, water, minerals and root area.
So,Competition is an relations between organisms or species in which both need a resource that is in limited pool.

Answer:
Plantlife, grow a garden. Animal life, raise some livestock. And a water source, most definitley.
Explanation:
The EMB (Eosin Methylene Blue) agar is a selective and differential agar medium. It contains sucrose and lactose as fermentable substrates together with Eosin Y and methylene blue dyes which in combination gives the agar its characteristic color when prepared and serves as a pH indicator as well as an inhibitor of growth of Gram-positive bacteria. Hence, it is primarily used to isolate Gram-negative fecal coliforms while some positive fecal coliforms such as Staphylococci are also able to grow.
These coliforms are of two types:
- Lactose or sucrose fermenting coliforms form metallic sheens on the agar as a result of acid production and the response of the indicator to the increased acidity.
- Non-lactose/sucrose fermenters are only able to produce acid by protein deamination. Hence they either form colorless or pinkish colonies on the agar
On the other hand, Mannitol salt agar is a selective and differential agar medium that is primarily used to isolate Staphylococcal bacteria. The presence of sodium chloride in the medium makes it a partial or complete inhibitor of other bacteria.
Hence, an unknown bacterium that forms colorless colonies on EMB will either be a non-lactose fermenting, Gram-negative coliform that will hardly grow on Mannitol salt agar, or a Gram-positive fecal Staphylococcus.
Staphylococci bacteria are of two types:
- Coagulase-positive will form yellow colonies on the Mannitol salt agar.
- Coagulase-negative will form red colonies on the Mannitol salt agar.

Correct option a) Increased plasma volume.
A potential negative health effect of stress is Shrinks the brain. Stress that's the left unchecked can contribute to many health problem, such as high blood pressure , heart disease , obesity and diabetes.
The volume of the brain tends to remain about the same, it has been found that chronic stress in healthy individuals can causes areas of the brain associated with emotions , metabolism and memory of that individual to be shrink slowly.
Stress can also be positive which is distress , getting job promotion or being given grater responsibilities keeping us alert and ready to avoid danger. It can became negative if a person faces continuous challenges without relief or relaxation between challenges.
