Answer:
Ecological footprint estimates the requirements of renewable resources that a population consumes to live a particular lifestyle. Some ecologists are concerned because the result of the ecological footprint shows that the demand of the population is increasing in comparison to the supply of nature.
For example in India, the ecological footprint shows negative impact of population demand over supply of nature.
The amount of total energy at each trophic level decreases as it moves through, so 90% is lost at each level. This means that only 10 percent of the energy at any trophic level is transferred to the next level; and the rest is lost as heat.
In this case, if a plant ecosystem has 3000000 kilocalories (kcal) of energy, about 300000 kcal will be transferred to primary consumers (for example grass hoppers). If the red-tailed hawks are tertiary consumers, they will get 3000 kcal of energy.
Answer:
The herbivory by the white-tailed deer
Explanation:
The independent variable can be defined as the variable that who's values do not depend on those of another.
The independent variable in this case is the herbivory by the white-tailed deer which is divided into two categories.
The dependent variables is the response of the corn to the independent variable which are measurements to be taken as shown in the question; the height of the corn plants and the number of ears or corn each plant produces.
Diploid cell. In meiosis I, the cell undergoes cell division process that is more likely has the similar procedures that mitosis undergoes. The cell produced is called the diploid cell which has the complete 48 strands of chromosomes within it. However, after the mitosis II takes place, the cell produced is called a haploid cell which has only 24 chromosomes instead of 48.
