Answer:
Oxidize organic compounds AND use organic compounds as terminal electron acceptors. (Ans. E)
Explanation:
Anaerobes are the organism that does not require oxygen for their growth. The anaerobes are subdivided into three main classes:
1) Obligate anaerobes: These organisms use anaerobic metabolism to grow and killed in the presence of oxygen. Obligate anaerobe examples are Clostridium and Propionibacterium.
2) Facultative anaerobes: These organisms prefer to grow using aerobic metabolism processes and switch to anaerobic metabolism in the absence of oxygen. An example of facultative anaerobic bacteria is Lactobacillus.
3) Aerotolerent anaerobes: These organisms use anaerobic metabolism to grow and can survive in both conditions (oxygen and oxygen-free environment).
Anaerobic bacteria, oxidize organic compounds rather than oxygen & use organic compounds as terminal electron acceptors. Anaerobic bacteria release hydrogen sulfide gas as they decompose algae in the water. This process is also known as Anaerobic Respiration, in which formation of ATP without oxygen.

Spores and seeds have basically the same function-dispersal-but are vastly different because spores (D) are unicellular; seeds are not.
<h3>What are unicellular organism?</h3>
A unicellular organism can be regarded as single-celled organism, which are those organisms that consists of a single cell.
This is different from multicellular organism because it consists of multiple cells however Organisms can be selected base on general categories which are prokaryotic organisms and eukaryotic organisms.
It should be noted that Spores and seeds have basically the same function-dispersal-but are vastly different because spores (D) are unicellular; seeds are not.
Therefore option D is correct.

The correct option is this: MARINE BIOLOGY IS THE STUDY OF ALL ORGANISMS FOUND IN THE OCEAN, WHILE OCEANOGRAPHY IS THE STUDY OF THE PHYSICAL, CHEMICAL AND GEOLOGICAL FEATURES OF THE OCEAN.
Marine biology is the scientific study of all the organisms in the sea while oceanography is the study of the physical, geological and the biological aspects of the ocean.
The type of organisms that take energy by eating up other organisms in an ecosystem are called 'CONSUMERS'. Now these consumers are further divided into three major classes:
1. Primary consumers: this type of consumers feed directly from the producers (plants) and they only eat grass, leaves, vegetables, etc. Such animals are also called herbivores. Example: rabbit
2. Secondary consumers: these are the animals that eat up primary consumers (animals that feed only on plants). These animals are called carnivores. Example: snake
3. Tertiary consumers: animals that eat carnivores which eats a herbivore are called tertiary consumers. They can be completely carnivore or omnivore (who feed on animals and plants both). Example: humans (they feed on animals and plants both)
