Answer 2

Nitrogen fixation. (Ans. D)

Step-by-step explanation:

Protists are unicellular micro-organisms. They share their physiological and morphological characteristics with both plants and animals. Protists can be similar to plants, fungus, and animals. That means that they can obtain food like plants, animals, and fungus.

There are many plants like protists, like algae they get their energy from sunlight through the process of photosynthesis. Some like fungus type and animal type protists are parasite they absorb nutrients from their host, harming the host in the process. Some animal-like protists must ingest food.

So, they obtain their energy from ingesting food, absorbing food, and photosynthesis process.
