Which characteristic do euglenoids are algae share?
1. both are fungus-like protists.
2. both can be autotrophic.
3. both have whip-like tails.
4. both are decomposers.

2. Both can be autotrophic.

Euglenoids or Euglena is a genus of single celled flagellated organisms. It belongs to the kingdom of protozoa. They are eukaryotic organisms, which are found in fresh water and saline water. They have chloroplasts, which is also found in plants, therefore, these are photosynthesizing organisms, hence making Euglena an autotrophic organism. They also acquire nourishment hetrotrophically, like animals. Algae are autotrophic organisms, they are organisms which belong to plant kingdom. They exhibit chloroplast to conduct photosynthesis in order to prepare their food.

Therefore, on comparing the characteristics in these two organisms, it can be concluded that both can be autotrophic in nature.

b) both can be autotrophic
