compare and contrast
heterotrophs cannot make their own energy, so they obtain it from eating other living organisms, such as autotrophs. what are the two different types of autotrophs, and which is more common on our planet?
i think photoautotrophs are more common.
heterotrophs and autotrophs
a key question what happens during the process of photosynthesis?
all animals obtain the chemical energy they need from the food they consume. animals are known as heterotrophs, which are organisms that obtain energy by consuming other organisms.
some heterotrophs eat plants and are known as herbivores. others, such as the heron, consume other animals and are known as carnivores. animals that eat both plants and other animals are known as omnivores. decomposers are heterotrophs that consume dead organisms and the wastes of living organisms. a mushroom is one example of a decomposer.
autotrophs are organisms that make their own food using an external source of energy. most autotrophs use sunlight as a source of energy and are known as photoautotrophs. chemoautotrophs use chemicals as a source of energy, and are found only near vents on the ocean floor. photosynthesis is the process by which photoautotrophs convert light energy into chemical energy. photosynthetic organisms include plants, algae, and bacteria known as cyanobacteria. nearly all life on earth depends on autotrophs that capture sunlight energy and synthesize high - energy carbohydrates—sugars and starches—that can be used as food.

Explanation:

Step1: Identify ATP components

The three - part structure of ATP is Adenine (a nitrogen - containing compound), Ribosome (a sugar), and three phosphate groups.

Step2: Answer question 1

The parts are Adenine, Ribosome, and 3 Phosphate groups as labeled in the structure.

Step3: Answer question 2

Ribosome is a type of sugar.

Step4: Answer question 3

The three phosphate groups contain high - energy bonds. When these bonds break, energy is released.

Step5: Answer question 4

ADP (Adenosine Diphosphate) gets converted to ATP (Adenosine Triphosphate) by the addition of a phosphate group. This process is called phosphorylation and requires energy input, often from metabolic reactions like cellular respiration or photosynthesis.

Step6: Answer question 5

ATP has a higher potential energy because it has an extra phosphate group with a high - energy bond compared to ADP.

Answer:

1. Adenine, Ribosome, 3 Phosphate groups
2. Ribosome
3. 3 Phosphate groups
4. By the addition of a phosphate group through phosphorylation
5. ATP
