Match the numbered terms to the description that follows. Choose all appropriate terms. A prokaryote that obtains both energy and carbon as it decomposes dead organisms is a(n): 1. autotroph 2. heterotroph 3. phototroph 4. chemotroph

Answer is option (2) and (4).

Prokaryotes that obtain both energy and carbon as they decomposes dead organisms - heterotroph and chemotroph.

Explanation:

(1) Autotrophs or Producers - Organisms that produce their own food and get the energy to make food from inorganic sources or sunlight. They are the base level of the energy pyramid of an ecosystem. The existence of all other organisms depends on autotrophs as they provide fuel for others. Examples of autotrophs are green algae, all plants, photosynthetic bacteria, etc.

(2) Heterotrophs or Consumers - Organisms that consume autotrophs or other heterotrophs since they cannot produce their own food. They absorb nutrition from other organic carbon sources such as plant or animal matter. The examples of heterotrophs are fungi, all animals, many protists and bacteria.

(3) Phototrophs - Organisms that capture photons from light and convert it to chemical energy to carry out different cellular processes.

(4) Chemotrophs - Organisms that obtain energy by breaking down or oxidation of organic or inorganic molecules such as ammonia,  carbohydrates, molecular hydrogen, sulfur, hydrogen sulfide, ferrous iron, etc through chemosynthesis.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
