Vertebrata
Vertebrata is a group that contains various organisms which possess vertebrae (backbones). Animals that belong to the group are called vertebrates, and they include mammals, birds, fish, amphibians, and reptiles. The backbones in the animals extends from the head to the tail, and it encloses and protects the main nerve cord. The body of vertebrates is divided into trunk, and tail regions. They also possess a unique tube shaped brain, a distinct head, and three pairs of sense organs.
A shell is considered as biotic (living) because it is a hard, rigid covering of many animals such as snail, sepia, pila, turtles, sea urchins. A shell is protective outer layer of these soft bodied animals. Shells are made of calcium carbonate in the form of calcite or aragonite crystallized in an organic matrix. Shells of other animals are composed of chitin, bone or cartilage. That's why a shell is considered as biotic (living).
Answer:
The correct answer is "because it came from something living".
Explanation:
In biology, a shell is defined as a protective structure of mollusks and crustaceans. A shell is considered to be biotic because it came from something living. Shells are not in fact alive as they are made of calcium carbonate and in some cases α-chitin, two non living materials. However, since mollusks and crustaceans are living beings, shells are considered biotic.

The process of converting carbon dioxide and water into sugar molecules, photosynthesis is 6CO₂ + 6H₂O→ C₆H₁₂O₆ + 6O₂, hence option A is correct.
Such as sugars, and storing this chemical energy is known as photosynthesis which indicates that the products, a sugar molecule, and six oxygen molecules, are created.
Green plants and a few other species create their food through a process called photosynthesis, which involves the utilization of water, carbon dioxide, and sunshine.
When light energy is absorbed by chlorophyll (implied by the arrow) from the reactants, six carbon dioxide molecules, and six water molecules.
Plants, algae, and certain microorganisms employ the process of photosynthesis to transform light energy into chemical energy.
Therefore, the commonly used notation for photosynthesis is 6CO₂ + 6H₂O→ C₆H₁₂O₆ + 6O₂, hence option A is correct.

Answer:
The first one is the photosynthesis equation.
Explanation:
Answer:
No
Explanation:
Some organisms require diffrent type of treatment to live, than others. They can just eat bacteria and live without the sun.
Ex. giant tube worms, etc.
Answer:
yes my friend.
Explanation:
All living organisms rely or the sun in part of energy.
we are also depend upon the plant . so we or organisms are depend upon the producers whereas the producers depend upon the other abiotic factors such as sunlight , oxygen , carbondioxide for prepareing food which is used by all living organisms for survive.
now, explanation
temeperature is transmit from hotter body to the coller body.
here, we have the sun as a hotter body
we are cooler body comperative to the sun.
so sun's heat is transmit to the all living organisms helps to give light , heat and solar energy also. sun is the prepetual source whose amount is neither increase nor decrease.
as you all know that, death body temperature is very low. because their body cannot get from the sun or from other sources.
so, if you cannot get the heat from other body you may die there.
by heating our body we get differnt kinds of energy and we can do our various works easily un our daily life.
so, sun is essential for all living organisms in part of energy.
B. primary consumer → producer → decomposer → secondary consumer
C. producer → secondary consumer → decomposer → primary consumer
D. producer → primary consumer → secondary consumer → decomposer
The Food web is a complex interaction between autotrophs and heterotrophs and how the energy flows through them.
Thus, the energy flow in a food chain starts from producers to consumers and is then degraded by decomposers.

Answer: it has to be D
Explanation:
the producers eats plants and the primary consumers feeds on the producers. the secondary consumers feeds on the primary consumers while the decomposer eats the dead
