Answer:

The correct answer is option (a) i and iv.

Explanation:

For option (i):

All the green plants contain chlorophyll which absorbs the sunlight.
Plants use sunlight, atmospheric carbon dioxide and water to form sugar (energy source) and oxygen through photosynthesis.
So, all the green plants contain chlorophyll so that they can prepare their own food.
So, option (i) is correct.

For option (ii):

Animals are not autotrophs because they depend on other animals and plants for food.
So, animals are heterotrophs.
So, option (ii) is incorrect.

For option (iii):

Carbon dioxide is an essential compound in the process of photosynthesis.
In photosynthesis, sunlight, atmospheric carbon dioxide and water are required to form sugar (energy source) and oxygen (waste product).
So, option (iii) is incorrect.

For option (iv):

Oxygen is liberated as a waste product during photosynthesis.
In photosynthesis in the presence of sunlight, atmospheric carbon dioxide and water are required to form sugar (energy source) and oxygen (waste product).
So, option (iv) is correct.

So, the correct option is (a) i and iv.

The statements (i) and (iv) are correct.

Explanation:

Option (i) is correct.

• Because it is true that green plants makes their own required food.

• Since they has the ability to make their own food that is why they are considered as autotrophs.

Option (ii) is incorrect.

• Because animals are heterotrophs. They are not autotrophic orgnaisms.

• Animals cannot make food for their own. For food, they have to depend on others like on green plants and that is why they are considered as heterotrophs.

Option (iii) is incorrect.

• CO2 is required by the plants for performing the process photosynthesis.

• Alongwith CO2, light and water is also required for this process.

Option (iv) is correct.

• In the process of photosynthesis, the product that is formes are: Glucose, oxygen and water.
