4. Flood plains are very fertile​

Answer 1

Answer:

answering 1 and 2

Explanation:

1. Wet clothes take longer time to dry on a humid day because in a humidity day the environment contains moisture due to which the process of evaporation doesn't occurs and the clothes remains wet.

2. Green plants use CO2 because to prepare food by the process of photosynthesis. Due to CO2 green plants are able to made food by their own.

Answer 2

Answer:

1.In humid weather it takes longer time to dry wet clothes because the moisture and water vapour are present in humid weather they gets slight absorbed by the clothes and clothes maintain their wetness due to this they take a longer time to dry and in humid weather they don't get enough sunlight to dry themselves

2.Green leaves use energy from sunlight through photosynthesis to chemically combine carbon dioxide drawn in from the air with water and nutrients tapped from the ground to produce sugars, which are the main source of food, fiber and fuel for life on Earth.
