Answer:

D. Chemoautotrophs

Explanation:

Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.

Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.

Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.

Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.

Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.

Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.

Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.

What are the parts of animal and find their function. ​
REY [17]

Answer:

<h2>⚪parts of animals are:</h2>

tail,claws,wings, beak ,fur , fins, she'll, feather.

<h2>⚪function of animal parts</h2>

<h3>tail:</h3>

Many land animals use their tails to brush away flies and other biting insects. Some species, including cats and kangaroos, use their tails for balance; and some, such as monkeys and opossums, have what are known as prehensile tails, which are adapted to allow them to grasp tree branches.

<h3>claws:</h3>

Claws may be adapted for scratching, clutching, digging, or climbing. By analogy, the appendages of other lower animals are frequently called claws. The claw's shape is ordinarily suited to the food-getting habit of the animal.

<h3>wing:</h3>

Wing, in zoology, one of the paired structures by means of which certain animals propel themselves in the air. ... The primary flight feathers on the distal portion of the wing create most of the propelling force in flight, while on the less mobile upper wing the secondaries provide the greater portion of the lift.

<h2>beak:</h2>

All birds have one beak. But it has evolved differently in each species to improve its functions in response to its environment. These functions include feeding themselves and their young, defending themselves, grooming their feathers, mating, regulating their body temperature or building nests.

<h3>fur:</h3>

Fur is a thick growth of hair that covers the skin of many different animals, particularly mammals. ... The fur of mammals has many uses: protection, sensory purposes, waterproofing, and camouflaging, with the primary usage being thermoregulation.

<h3>fins:</h3>

Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluids. ... Fish, and other aquatic animals such as cetaceans, actively propel and steer themselves with pectoral and tail fins

<h3>shell:</h3>

Turtles and tortoises are some of the best-known shell-dwelling creatures. The difference between them is that tortoises live on land while turtles prefer the water

<h3>feather:</h3>

Feather Function: What do feathers do? Each feather on a bird's body is a finely tuned structure that serves an important role in the bird's activities. Feathers allow birds to fly, but they also help them show off, blend in, stay warm, and keep dry.

What accurately describes a difference between fungi and plants?
amm1812

Fungi are different from plants in that they are achlorophyllous.

<h3>Fungi vs plants</h3>

Fungi and plants are both eukaryotic in nature when it comes to their cells.

However, plants differ from fungi in that plants contain a green pigment known as chlorophyll while fungi do not. The green pigment enables plants to photosynthesize.

Thus, fungi are said to be achlorophyllous.
