WHY ARE THE TROPHIC LEVELS AND ENERGY REPRESENTED IN THE FORM OF PYRAMIDS?

Answers

Answer 1

Answer:

An energy pyramid shows the distribution of energy among trophic levels. Producers use energy from sunlight to make food. Herbivores eat plants—the producers—to get energy. ... Each level above gets smaller, because as energy is lost as heat, there is less energy avail- able as food for organisms.

Answers

Answer:

fertilized egg

Explanation:

Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Britannica

Answer:

A zygote is a eukaryotic cell that is produced when two gametes fertilize each other. The genome of a zygote is made up of the DNA from each gamete and includes all of the genetic information needed to create a new person. The zygote is the most basic developmental stage of multicellular organisms.

Whiteflies are common pest insects found on cotton, tomato, poinsettia, and many other plants. Nymphs are translucent and mostly sessile, feeding on their host plant's phloem (sap) from the undersides of leaves. They undergo incomplete metamorphosis into winged adults. Because whitefly nymphs cannot escape predation by moving, you hypothesize that their translucent bodies make them hard to spot by predators. How could you directly test this hypothesis?

Answers

Answer: Comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

Explanation:

A hypothesis refers to an assumption, which is proposed for the sake of an argument which is tested to ascertain if it's true.

The hypothesis can be tested by comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

Hey there!

Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunligh, so we eat the plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the reen pigment found in the chlorookasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

C

It has risen at an increasing rate throughout time. This rate hasn’t been steady due to many reasons. See the attached photo for details.

Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.

Earth's population over the centuries has risen at an increasing rate. So, the correct option is C.

How the population of Earth is increasing?

This sharp increase in population has been primarily caused by an increase in the proportion of individuals reaching breeding age, the gradual extension of human life expectancy, growing urbanization, and quickening migration. This expansion has been accompanied by significant changes in the fertility rate.

One of the key reasons for India's population expansion is a drop in death rates brought on by better medical services and a steady birth rate. The widespread illiteracy in India makes people believe that "children are god's blessings," which makes them opposed to the idea of "family planning." Earth's population over the centuries has risen at an increasing rate.

Therefore, the correct option is C.

What statements are true about glycolysis?
Select all that apply.

it produces ATP that can be directly used by cells
o it does not directly require oxygen to operate
o it produces more ATP than any of the other respiration reactions

Answers

Answer:

 true it consumes some ATP as well as producing it

true it produces ATP that can be directly used by cells

true it does not directly require oxygen to operate

false it produces more ATP than any of the other respiration reactions

Glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

What is ATP?

ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. It is a byproduct of the photophosphorylation, cellular respiration, and fermentation processes and serves as the primary energy currency of the cell.

Glycolysis is defined as a chain of events that convert glucose into two pyruvate molecules, which have three carbons each. Glycolysis is a cytoplasmic process that breaks glucose down into two molecules with three carbons apiece and releases energy. Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose.

Thus, glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

A period happens because of changes in hormones in the frame. Hormones are chemical messengers. The ovaries launch the lady hormones estrogen and progesterone . those hormones motive the liner of the uterus (or womb) to build up. The constructed-up lining is prepared for a fertilized egg to connect to and begin developing. If there is no fertilized egg, the liner breaks down and bleeds. Then the identical manner occurs all once more.

 

It normally takes about a month for the liner to build up, then smash down. this is why a lot of ladies and women get their periods round once a month.
