In the trophic system, herbivores are referred to as “primary consumers” since they are the first animals to consume producers. They are also the carriers of photosynthetic energy. Thus, option C is correct.
What is herbivore?
An animal that has evolved physically and physiologically to eat primarily plant matter, such as foliage or marine algae, is called a herbivore.
Herbivorous animals often have mouth parts adapted to rasping or grinding due to their diet of plants.
An animal or insect that only consumes plant material, such as grasses, fruits, leaves, vegetables, roots, and bulbs, is known as a herbivore.
Only living creatures that require photosynthesis are consumed by herbivores. Insects, spiders, fish, and other creatures are not included in this.
Therefore, herbivores are referred to as “primary consumers”

Which statement describes an event that occurs during glycolysis that contributes to the production of ATP?
A. Pyruvic acid is broken down to form carbon dioxide.
B. Oxygen molecules are broken down and converted into pyruvic acid.
C. High-energy electrons and hydrogen ions are passed to NAD+ forming NADH.
D. Carbon atoms in glucose are transferred to ADP, forming ATP.
Answer:
C. High-energy electrons and hydrogen ions are passed to NAD+ forming NADH.
Explanation:
The sixth step in glycolysis is the first of the two-energy-conserving reactions of glycolysis which results in the formation of ATP. This step involves the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate.
In the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate, high-energy electrons and hydrogen ions are passed to NAD⁺ forming NADH.
Glyceraldehyde-3-phosphate + inorganic phosphate + NAD⁺ ----> 1,3-bisphosphoglycerate + NADH + H⁺
The NADH produced in this reaction transports the high-energy electrons passed to it through the electron transport chain to produce ATP in oxidative phosphorylation.
How does carbon dioxide concentration affect photosynthesis rate?
Answer:
An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction - and so the rate of photosynthesis generally increases until limited by another factor.
Explanation:
CO2 concentration is directly proportional to rate of photosynthesis.
CO2 is raw material for process of photosynthesis.
CO2 + H2O → C6H12O6 + O2
Increase in CO2 concentration increases rate of photosynthesis.
Decrease in CO2 concentration decreases rate of photosynthesis.
Therefore, CO2 concentration is limiting factor for rate of photosynthesis.

(A) True or (B) False: Two species of lizard with the same thermal niche could coexist in the same range.
The statement "two species of lizard with the same thermal niche could coexist in the same range" is true.
What is species?Species is the term that is used to classify different organisms. Species is the second last classification, which means most similar organisms are present in this classification. The traits are mostly similar in these organisms.
Two species of lizards are given the same thermal niche. So these lizards have similar characteristics of thermal niches. So these lizards can live in the same range because they can coexist. But in these organisms, there can be competition between them.
The statement can be true as it can coexist in the same range as they have a similar thermal niche. They can live in the same temperature.
Therefore, the statement is false.

Prior do the 1600s it was believed that all living things for either plants or animals. Which of these inventions led to the development of a more detailed classification system
Answer:
The Microscope
Explanation:
Before the 1600s, every living thing was a part of a two kingdom classification system derivative of binomial nomenclature. This was proposed by Linnaeus, a Swedish Naturalist, who split all living things into either the animalia or plantae kingdom. After the invention of the microscope however, a new detailed classification system was put in order to accommodate for microscopic life. This new system recognizes the existence of 6 kingdoms: eubacteria, archaebacteria, prostista, fungi, plantae, and animalia.

All of the following is true of GMOs EXCEPT
A. They have increased food production
B. Only animals are modified genetically
C. They can increase resistance to disease
D. Many are concerned that the full impact of GMOs on people is not known
Only animals being modified genetically is not true of GMOs. Genetically
modified organisms(GMOs) usually undergo some changes to their DNA in
order to infuse beneficial trait such as size and taste, resistance to diseases
etc.
The infused trait through DNA alteration helps to increase the quality and
yield of crops thereby making them readily available for the population.
Plants and animals undergo this process and isn't restricted to animals

Photosynthesis is the process by which producers convert energy from the Sun into chemical energy in the form of glucose. Explain why photosynthesis is so important for ecosystems.
Answer:
Some animals feed on plants which make their food through photosynthesis, and most animals feed on animals which feed on plants so, without photosynthesis most living things may go extinct. Right from ma brain
Explanation:
PLZ give a crown
Answer:
plants are called photosynthetic autotrophs...
WHY ARE THEY CALLED PHOTOSYNTHETIC...?!? because they convert light energy (i.e. sunlight) to chemical energy (i.e. glucose) this process is called photosynthesis. The Photosynthetic formula is 6CO2 + 6H2O ---> GLUCOSE + 6O2......
WHY ARE THEY CALLED AUTOTROPHS....?!? because they make their own food by using inorganic sources that is Water and Carbon dioxide. they are fully independant from other organism. So they do not feed on any other organism for survival hence they are found on the bottom of the energy pyramid so if they wouldn't convert light energy into chemical energy all the animals would be dead because we are not autotrophs we can not make our own food by using inorganic sources we need already made organic food thats why those organisms which can not make their own food are called heterotrophs
