class 10 science

Answer 1

Different kind of organisms obtain thier food in different ways.
The process of obtaining food is called nutrition. Nutrition is of two types namely 1) HETEROTROPHIC And 2) AUTOTROPHIC.

Heterotrophic nutrition : It means organisms depend on other animals for thier survival.
All animals and non green plants are heterotophs.

Autotrophic nutrition : It means that the organisms make thier own food by using sunlight. All plants and photosynthetic bacteria are autotrophs.

Answer 2

Organism obtains their nutrition in the following way:

There are two forms of nutrition:

1. Autotrophic
2. Heterotrophic

• Autotrophic animals use sunshine to produce their food.
• Heterotrophic creatures rely on the help of others to survive.

• Food can be taken in by the entire surface of single-celled organisms.
• Amoeba, for example, takes in food by producing a food-vacuole with transient finger-like extensions of the cell surface that fuse over the food particle.
• Complex compounds are broken down inside the food vacuole into simpler ones, which then diffuse into the cytoplasm.
• The remaining undigested material is pushed to the cell's surface and discarded.
