Why does each species have its own niche?
Because each species has to have its own role in the environment
How can competition between species influence the niches of both pecies?
Species that occupy different niches are not likely to compete. This is because each of the species will probably eat different things and seek different types of shelters. They will not need each other's resources.
What can two organisms not do according to the biological species concept?
According to the biological species concept, two organisms are of different species if they do not do which of these
What does a single ecosystem include?
Various populations on species interacting with each other.
How is it that each species reproduces its own kinds?
It is genetically encoded and that is passed on to the offspring.
Why are invasive species dangerous?
They can affect the chemical makeup of the water, availability of resources, and even alter the food web. Invasive species impact other species more directly through competition for resources. Because invasive species evolved with other competitors and native species evolved in the absence of invasive species they lack the ability to compete with invasive species. They are costly to society in many ways through both, direct management, and decreased production. The annual estimated cost in the United States of invasive species control is about 120 billion dollars per year. It is estimated that the global cost of invasive species management is equal to five percent of the global economy.
Researchers want to use eDNA to look for an invasive species in a waterway. Which of these steps should they do first?
precipitate DNA in each sample
What are major threats to the forest?
The major threats to any habitat or species can be summarized with the acronym HIPPO. Habitat destruction Invasive species Pollution Population growth (of humans) Overexploitation Each one of these threats reduces biodiversity, and destroys habitats, such as forests all around the world.
Will the cost control be a good topic for MBA finance?
Yes, I like this topic very much. In cost control the factors of economics and finance are integrated with each other which makes it a perfect topic.
How does competition within species control the population?
Animals of a species kill each other for food, water, shelter, etc. and the deaths keep the population from getting too high.

What is intraspecific association?
Intraspecific association is a relationship between members of the same species. When resources are limited, the members will fight each other for control.
What are the various objective of cost accounting?
Important objectives of cost accounting:The primary objectives of cost accounting is to determine the cost of each product, process, job, operation or service rendered.Cost accounting determines the profitability of each product, process, job, operation or service rendered.Cost accounting classifies cost into different elements such as materials, laborer and overhead. It is further divided as direct and indirect cost for cost control and recording.Cost accounting aims at controlling cost by setting standards and comparing those with the actual, the deviation or variation between the two is identified and necessary steps are taken to control them.
Describe how to measure species richness and species evenness. (supplemental resource?
species richness is the total number of species present if there are 4 species present and 5 of each then the species richness is 4 as there is 4 types of species while the species evenness is 5 a species eveness is the relative abundance of each species.
How much money do live geckos cost?
Gecko species can vary in price depending on what species you are looking for. Species that are more common in the reptile hobby can range from $5 - $50. Most gecko species that people keep range from $50-$250+ (includes: fat tails, cresteds, leopards, viper).
