Wolves prey heavily on beavers in a temperate forest ecosystem. The diet of beavers consists of the leaves, branches and bark from trees, as well as many types of aquatic vegetation. In this relationship, what is the role of the wolves? A producer B decomposer C primary consumer D secondary consumer
Answer:
In this relationship , the role of wolves is as Secondary Consumers .
Explanation:
A PRODUCER - Producers are referred to as an organism that prepares its own food. Often, they are called autotrophs.
All the green plants, for example.A DECOMPOSER -: Decomposers are organisms which break down organisms and waste that are dead or decaying. Their function is ecologically important as they recycle the nutrients through a natural biological process (decomposition).
Fungi and bacteria that derive their nutrients from dead plant or animal matter are examples of decomposers.PRIMARY CONSUMERS -: Typically, primary consumers are herbivores-animals that eat plants. Since they have to eat other items to survive, they are called heterotrophs. This is different from farmers who make their own food and are autotrophic.
Insects, mice, and deer are common examples of this type of product.SECONDARY CONSUMERS -: The secondary consumers are species that eat energy from the primary consumers. Only other animals eat carnivores, and omnivores both eat plant and animal matter.
You can find secondary users, such as dogs , cats, moles, and birds, in temperate areas , for example. Foxes, owls, and snakes are other examples. Examples of secondary consumers that receive their energy from primary consumers by scavenging are wolves, crows, and hawks.In the given foodchain , the wolves are consuming beavers as their food and beavers consume leaves , branches and twigs as their food. Therefore , it is cleared from the above definations , that leaves and branches consumed by the beaver are producers(as they are the part of plants ) , the beavers are herbivores dependent on green plants , so they are primary consumers and the wolves who are preying on beavers are secondary consumers as they are carnivores .
Hence, the correct answer is OPTION D.

Explain why primary ecological succession usually takes hundreds or thousands of years.
Chose ALL the choices that are true about exponential growth: a Rapid (fast) period of growth b Has carrying capacity c "S" curve d "J" curve e Takes place when there are lots of resources ex: food, space f Takes place when there are limited resources ex: food, space
Answer:
a, d, and e
Explanation:
The exponential growth is a period characterized by rapid growth as a result of the availability of unlimited resources for the use of the population. Once the population spends a short period getting acclimatized to their environment, a period of rapid growth follows that is devoid of any limitation and thus, the growth curve forms a 'J' shape. This type of growth has no carrying capacity that limits its growth and may not be possible in real life where resources are limited.
The correct options are a, d, and e.

O deltas
O gullies
O flood plains
O stalactites
Gullies are a feature that may form as a result of erosion related to runoff. It may produce the transfer of water from fields to adjacent land.
What is runoff erosion?Runoff erosion is a natural process that produces the transfer of water from fields to adjacent land.
The runoff may lead to erosion because the eroded material in the soil can be deposited a significant distance away.
This process (runoff related to erosion) occurs when there is more water or any other substance (for example, pesticides) than the land/soil can absorb.

When snow covering the ice sheet blow away, there is an increase in oxygen bubbles trapped under the ice. Explain why this occurs
Answer:
Impurities are trapped between layers of ice over the years.
Explanation:
As time goes on, many chemical impurities and gases are trapped between deposits of ice that form over the years in extremely cold regions such as Antarctica.
When the snow covering these layers of ice are removed, the gases trapped underneath are released and more oxygen dissolves in the ice and more bubbles are observed.

Imagine that you are given 25 germinating pea seeds that have been placed in 5M hydrochloric acid for five minutes. You place these seeds after you rinse them off, in a respirometer at the end of the five minutes and collect data. Predict the rate of oxygen consumption for these seeds and explain your reasoning.
Answer:
In the respirometer, it will be present no significant values of oxygen from the respiration process. The acid can denature proteins in a non-functional shape.
Explanation:
The pH of the solution will be considerably low in order to the proteins to work normally. In this case, the polarization of sites in the protein will cause a completely denaturation.
A normal pH is essencial for the best working coefficient of enzymes an proteins in general as well as temperature.

Whats the difference between bacteria cells, and blood cells?
Answer:
recent study out of the Weizmann Institute in Israel states that the number of bacteria may actually be very similar to the number of human cells in the body.
While this results in about 1.3 bacterial cell per human cell, the numbers may vary significantly from person to person and could change significantly with each defecation. They estimate that the range of bacterial cells goes from about 30 to 50 trillion in each individual. Women may also have a higher ratio of bacterial cells than human cells because they have fewer human cells, specifically red blood cells.
What statement is true regarding active transport
Answer:
Substances can move from areas of low concentration to high concentration.
Explanation:
For the first one, substances CAN move in and out of cells in an active transport.
As for the second one, active transports do require energy. That is what makes them "active" and sets them apart from passive transports which don't require energy.
Lastly, substances can move across a membrane regardless of if they are water soluble (such as lipids, or fats that the cell does not use. Think of it as a way for the cell to eat, drink, and defecate or remove waste.)
