Was it beneficial or harmful for the Chthamalus barnacle to add the Balanus barnacle? Explain.
Answers
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.
Where does the stench come from the is in your arms?
Answers
Answer:
The human armpit has a lot to offer bacteria. It's moist, it's warm, and it's usually dark. But when the bacteria show up, they can make a stink. That's because when some kinds of bacteria encounter sweat they produce smelly compounds, transforming the armpit from a neutral oasis to the mothership of body odor.
Explanation:
Body odor is caused by bacteria breaking down sweat and is largely linked to the apocrine glands. ... They are scent glands. The apocrine glands are mainly responsible for body odor because the sweat they produce is high in protein, which bacteria can break down easily.

Can you write a two-page paragraph explaining invasive species please? Thank you.
Answers
Answer:
Invasive species, also called introduced species, alien species, or exotic species, any nonnative species that significantly modifies or disrupts the ecosystems it colonizes. Such species may arrive in new areas through natural migration, but they are often introduced by the activities of other species. Human activities, such as those involved in global commerce and the pet trade, are considered to be the most common ways invasive plants, animals, microbes, and other organisms are transported to new habitats.
Most introduced species do not survive extended periods in new habitats, because they do not possess the evolutionary adaptations to adjust to the challenges posed by their new surroundings. Some introduced species may become invasive when they possess a built-in competitive advantage over indigenous species in invaded areas. Under these circumstances, new arrivals can establish breeding populations and thrive, especially if the ecosystem lacks natural predators capable of keeping them in check. The ecological disruption that tends to follow such invasions often reduces the ecosystem’s biodiversity and causes economic harm to people who depend on the ecosystem’s biological resources. Invasive predators may be so adept at capturing prey that prey populations decline over time, and many prey species are eliminated from affected ecosystems. Other invasive species, in contrast, may prevent native species from obtaining food, living space, or other resources. Over time, invading species can effectively replace native ones, often forcing the localized extinction of many native species. Invasive plants and animals may also serve as disease vectors that spread parasites and pathogens that may further disrupt invaded areas.Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

Explanation:
bryozoan - "Bryozoa are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia." -Wikipedia
rotifers - "The rotifers, commonly called wheel animals or wheel animalcules, make up a phylum of microscopic and near-microscopic pseudocoelomate animals." -Wikipedia
cnidarians - "Cnidaria is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments: they are predominantly marine. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick.
" -Wikipedia
mollusks - "Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda. The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high." -Wikipedia

Answer:
Experimental set up in the lab.are under the control of the scientist,therefore they can manoeuvre the the surrounding conditions to suit the experimental set up for best results. In addition the lab.environment does not involve the complex interactions or reaction between the set up and the lab. environments, compare to the natural environment.
Natural experimental set up gives accurate results from the interaction of the organisms(e.g animals) under investigation in the natural environments,thus the results obtained are natural interaction of the organisms based on the environmental factors the organism are exposed to.However, the number of organisms are usually large,and therefore great effort is needed to determine the actual cause and effects of the factors affecting the organisms under investigations in this natural environments.

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
Answers
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 is water pollution a concern if water is continuously cycled through Earth’s systems?
Answers
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.
