Was it beneficial or harmful for the Chthamalus barnacle to add the Balanus barnacle? Explain.
Answer:
It was it harmful for the Chthamalus barnacle to add the Balanus barnacle.
Explanation:
The principle of competitive exclusion says that two different species that share the same niche can not live in the same place. If these species have the same requirements, they can not coexist. Two species can not coexist indefinitely on the bases of the same limited resource.
When two competing species coexist, this is because of niche partitioning or niche differentiation. If there is not any differentiation between them, the dominant species displaces the weak species.
In the exposed example, Chthalamus can live in the upper intertidal zone, where Balanus can not live because they can not tolerate desiccation. Balanus live in the lower intertidal zone, where Chthalamus can not live because of its vulnerability to predation. But these two species compete for the middle intertidal zone, where they can both live. Balanus excludes Chthalamus because the first species is much bigger and grows faster than the second one. So the middle intertidal zone is only inhabited by Balanus.
The area occupied by Chthalamus is smaller in the presence of Balanus. In the absence of Balanus, Chthalamus can live in a bigger area, occupying the middle intertidal zone.

A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type of
limiting factor causes this?
Odensity dependent
Odensity independent
O population dependent
population independent
Answer:
density independent
Explanation:
In Ecology, a limiting factor refers to an environmental condition that hinders the growth and distribution of organisms in an ECOSYSTEM. A limiting factor hinders or hampers the productivity of an organism in its habitat.
There are two major types of limiting factors that affect organisms in their ecosystem viz: density dependent and density independent limiting factors. Density independent factor limits the size of a population independently of how dense the ecosystem's population is. This means that density independent factor affects a population irrespective of its size. Example of density independent factor are natural disasters e.g earthquake, hurricane, forest fire as mentioned in the question.
In this question, both populations of trees and birds are affected irrespective of the size of the ecosystem's population.

why/how is biodiversity essential to the health of an ecosystem
Answer:
Biodiversity is the amount of variety of life on Earth.
Explanation:
Biodiversity boosts ecosystem productivity where each species, no matter how small, it has an important role to play.
For example,
a larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all forms of life.
Because it provides a wide variety of ecological services essential to both ecosystem function and human well-being, biodiversity is important to the health of an ecosystem.
What is Biodiversity?The term "biodiversity" describes the range of living things in an ecosystem, such as plants, animals, fungi, and microorganisms, as well as the genetic diversity found within each species.
Here are some justifications for why ecosystem health depends on biodiversity:
1. Nutrient Cycle: The ability of an ecosystem to cycle nutrients depends on biodiversity.
2. Temperature control: By absorbing carbon dioxide and generating oxygen through photosynthesis, biodiversity helps regulate temperature.
3. Soil health: Biodiversity is essential for the preservation of healthy soil.
4. Controlling pests and diseases in ecosystems: Biodiversity can help in managing pests and diseases.
5. Benefits to the Economy: Humans benefit economically from biodiversity in a number of ways, including access to food, medicine, and other natural resources.
Therefore, biodiversity is important for the health of ecosystems, and its loss can have serious detrimental effects on both ecosystem functioning and human well-being.

Calculate if 1000 units of energy are available at the producer level of the energy pyramid about how many units are available for first level consumers? Second level consumers? Third level of consumers?
Answer:
first level consumers?- abou 100 units
Second level consumers- about 10 units
Third level of consumers- about 1 unit
Explanation:
Food chain describes the feeding pattern of a group of organisms in an ecosystem. The food chain shows how one organism in one TROPHIC LEVEL feeds on another organism in another. As organisms are being fed on, energy is being transferred.
A food chain always starts with a PRODUCER, which occupies the first and lowest trophic level. It creates the energy transfer as it obtains energy via photosynthetic process. The flow of energy as shown by an energy pyramid is Producer----First level consumer----Second level consumer------Third level consumer.
However, only about 10% of the available energy is transferred and accessible by the next organism. This is because about 90% of the energy has been lost as heat when the organism undergoes metabolic processes. Hence, if 1000 units of energy was present at the producer level, 10/100 × 1000= 100 units will be available to first level consumers.
Also, 10/100 × 100= 10 units of energy will be available to second level consumers and finally 10/100 × 10= 1 unit of energy will be available to talk third level consumer.

Why is water pollution a concern if water is continuously cycled through Earth’s systems?
Water pollution is still a concern, even though its cycled through the Earth's system continuously, for many reasons. Firstly, people still continue to dump toxic chemicals, and plastic/ garbage into the water. Plastic doesn't decompose, it continues to sit and pollute the ocean unless it is cleaned up. Then there are also the chemicals. Some of these chemicals don't dissipate, or clear out for many years. There is also oil that has been spilt into the ocean. Even though it was many years ago, it still lingers in the ocean, and is very difficult to clean up. Secondly, there are bacteria and algae that lives in the water, which makes it very harmful for us if not cleaned out. The Earth's system is unable to keep these organisms out of the water. Thirdly, there is constantly water, even though water goes through the cycle, there is still unfiltered polluted water that stays, and then pollutes the filtered water.

A. One of the late symptoms of MN is excessive edema, or build up of fluid within the interstitial space of tissue. Explain how loss of circulating blood protein (hypoalbuminemia) would cause edema with respect to hydrostatic and colloid osmotic pressure within capillary beds throughout the body.
Answer:
Albumin is a protein that attracts water in the compartment where it is found, that is why when circulating within the blood vessels the blood volume is maintained by this protein, so that the liquid or fluid that makes up the blood volume is retained within the capillaries due to hydrostatic forces and because the albumin protein is hydrophilic.
The albumin is decreasing, that is, in deficit or hypoalbulinemia, less water reaches the blood compartment, therefore the blood pressure or pressure will drop, the blood volume will decrease but not due to loss of it as in hemorrhages, but due to diffusion to other compartments. VASCULAR through the processes of OSMOSIS, in simple words, when this protein descends, water filters from the blood vessels to extravascular compartments, this phenomenon clinically manifests itself as EDEMA.
Explanation:
Hypoalbulinemia also occurs in severe nutritional disorders where ovalbumine is not consumed through the egg, since the person's diet is severely lacking, generating massive edema in the abdominal area or abdominal distension.
The effect that the plasma liquid has in spreading to extravascular spaces is called OSMOSIS, which draws water from the external environment by the oncotic pressure generated by other proteins.
The oncotic pressure is the pressure that is generated when the water diffuses from one compartment to another by attraction of a protein, it happens both with albumin and with other proteins of the organism that are characterized by being hydrophilic or attracting water.
Hypoalbulinemia destroys severe cardiac symptoms due to the high demand that an increase in edema and difficulty of venous return entail along with the fall in blood pressure.
