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

What observations and evidence support the theory of evolution?.

Answers

Answer:

direct observation, the existence of homologies and fossils, and certain biogeographical patterns.

Explanation:

Fossils:
These provide solid evidence that organisms from the past are not the same as those found today, and fossils show a progression of evolution. Scientists determine the age of fossils and categorize them from all over the world to determine when the organisms lived relative to each other. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

Molecular Biology:
Like anatomical structures, the structures of the molecules of life reflect descent with modification. Evidence of a common ancestor for all of life is reflected in the universality of DNA as the genetic material and in the near universality of the genetic code and the machinery of DNA replication and expression. Fundamental divisions in life between the three domains are reflected in major structural differences in otherwise conservative structures such as the components of ribosomes and the structures of membranes. In general, the relatedness of groups of organisms is reflected in the similarity of their DNA sequences—exactly the pattern that would be expected from descent and diversification from a common ancestor.

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

(A) True or (B) False: Two species of lizard with the same thermal niche could coexist in the same range.

Answers

False

Explaining: False

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.

How does carbon dioxide concentration affect photosynthesis rate?

Answers

Increasing the concentration of carbon dioxide increases the rate of photosynthesis, as there is a greater supply of it that can be used. Of course, you can only add so much carbon dioxide before the plant can’t perform photosynthesis at an any faster rate. Increased carbon dioxide concentration will increase the rate of photosynthesis until it is no longer the limiting factor in the reaction.

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.

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.

Answers

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.

Answers

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.
