Answer:
a. eukaryotes
b. unicellular
c. autotrophs; heterotrophs
Explanation:
Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.
Ok. so first, the answer is c. then a. then c again. then b. then finally, d. hope this helps!
Actually yes. You can find organisms, like bacteria, living in deep oceans, which do not have access to sunlight. There are cases in which they use thermal resources in order to produce energy. They are called <span>chemoautotrophs. You can find them around deep ocean "smokers".</span><span />
