Answer 1

Answer:

1. Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy.

2. Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Rhizobium species form an endosymbiotic nitrogen-fixing association with roots of legumes and Parasponia.

3. Amarbel is an example of Parasite. Amarbel is also called as Cuscuta or Dodder. The organism that grows on the body of another organism and derives nutrients from it is known as a parasite.

Hope this helped...
