In a food pyramid, there is typically less biomass at the top (i.e., there are very few individual tertiary consumers, whereas there are numerous individual producers). In three to five sentences, explain this phenomenon, citing evidence relating to energy flow and how plants support ecosystems.
Answers
It is because of the 10% rule in the ecosystem, there are generally less biomass at the top.
The energy transfer in ecosystems:It is found that only 10% of the energy stored as biomass in a trophic level is carried forward to the next trophic level. This is called the 10% rule, due to this rule, the number of trophic levels an ecosystem can support is limited.
As one goes up in the food chain, only 10% of the energy is passed on to the next level, that is, about 90% of the energy is lost in the form of heat. At the bottom of the trophic level, there are producers, that is, plants, they get their energy from the Sun.
Further the plants are consumed by the primary consumers, and the energy is passed on. However, in the process, only 10% of the energy is passed on and the rest is lost in the form of heat. Further the primary consumer is consumed by the predator, which comes at the top of the food chain.
During the consumption of primary consumer, the same 10% energy is passed on and the rest is lost. This process continues and the energy is lost in the form of heat. With less energy at the top of the trophic level, only few individuals can be supported. This is the reason of less predators in comparison to prey.
Thus, it is the 10% rule, which results in lesser number of tertiary consumers in comparison to producers.

It is because of the 10% rule in the ecosystem, there are generally less biomass at the top.
Briefing:Only 10% of the energy produced by primary producers is used by consumers; the remaining 90% is wasted. Let's assume that a fox consumed a rabbit that had previously consumed grass and had retained 10% of its energy. As a result, the fox will only receive 1% because 10% of 10% is only 1%, and this will continue to trickle down to tertiary customers. In order for primary consumers to exist and for secondary consumers to be able to survive without primary consumers, ecosystems need plants, or primary producers. (Equally true for tertiary consumers).
Who is a Tertiary consumer?Quaternary consumers pounce on tertiary consumers. These quaternary consumers are frequently the apex predators, which indicates that their ecology is devoid of any predators. Animals like lions, polar bears, sharks, and hawks are some examples of quaternary consumers.

According to CDC, between 1998 and 2011, about 79% of the dairy-related illness outbreaks were caused by
cheese or raw milk (unpasteurized) products. 148 outbreaks and 2,384 illnesses were reported during that time.
284 required hospitalizations and 2 deaths were caused by cheese or raw milk products. Although these numbers
seem small, there are risks. At a federal level, although the FDA forbids the sale or distribution of raw
(unpasteurized) milk, 13 states allow the sale of raw milk in their retail stores, and another 17 states allow the
sale of raw milk on the actual farm that the milk was produced.
Explain the thinking that caused the FDA to forbid the sale and distribution of raw milk.
A)
Unpasteurized milk has the shortest shelf-life.

A population of rabbits lives on one side of a wide river. Another population of rabbits lives on the opposite side of the river. They cannot cross the river. If speciation occurred as a result of the river, what kind of speciation was this? ___________
Answers
Answer:
Allopatric speciation
Explanation:
The kind of speciation that occurs when 2 populations of rabbits separated by water become different species is allopatric speciation.
Allopatric speciation occurs when two populations of the same organisms become physically separated and each population ends up developing unique characteristics that make them distinct species. This is as opposed to sympatric speciation in which a new species just spontaneously emerge from the existing population without any being separated from the population.
Other forms of speciations include parapatric speciation which occurs as a result of the spreading out of a population over a large geographical area and peripatric speciation which occurs as a result of the breaking off of a small group from a large group of organism.
In the illustration, the two populations of rabbits are separated physically by the river. Hence, the speciation that will occur if each population goes ahead to form a new species would be allopatric speciation.

What did Avery conclude caused transformation?
a. DNA was the transforming factor.
b. A protein was the transforming factor.
c. A carbohydrate was the transforming factor.
d. A lipid was the transforming factor.
Answers
Answer:
The answer is B
Explanation:
Avery concluded that DNA was the transforming factor. Therefore, the correct option is A.
Based on his research from the 1940s, Avery came to the conclusion that DNA was modifying the organism. Avery, along with his colleagues Colin MacLeod and Macklin McCarty, worked through a series of carefully planned experiments to pinpoint the precise element responsible for the transmission of genetic information in bacteria.
They tried to identify the transforming factor by treating the heat-killed bacteria with various enzymes that specifically destroy various cellular components such as proteins, carbohydrates, RNA and DNA. When the scientists exposed the bacteria to DNase, an enzyme that selectively breaks down DNA, they made their breakthrough discovery. He observed that the ability to transmit genetic information was lost when DNA was damaged.
Therefore, the correct option is A.

The image shows a spruce tree, which is a gymnosperm.
Which characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant?
naked seeds
green leaves
thick bark
tall height
Answers
Answer: Naked Seeds
Explanation:
Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.
The exposed seeds characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant.
What is gymnosperm?Gymnosperms are a small category of plants that don't blossom and produce "exposed seeds."
Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.
Many gymnosperms bear their seeds in cones, which are known as "exposed seeds" because they are not visible until they are fully developed.
This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
Therefore, option A is correct.

What forms as a result of the wind's frictional force on water?
O deep sea currents that move in a path opposite to the wind currents
O surface currents that move in a path opposite to the wind currents
surface currents that move in a path similar to the wind currents
deep sea currents that move in a path similar to the wind current
Answers
Answer:
Surface currents that move in a path similar to the wind currents
Explanation:
One of the reasons of the movement of the surface of the oceans is the force of the blowing wind. When there is a movement of wind over the surface of the ocean, the surface friction is created. Because of this there is an energy transfer between the force of the wind and the surface of the ocean water. This results in the creation of roughness of the surface of the ocean. The more the surface area of the ocean, the more is the transfer of the energy.
