What do the arrows represent in the figure

Flow of  energy in ecosystem.

Explanation: The picture here represents the flow of energy from the producers to consumers.

The first picture shows the plants that takes energy from the sun for the production of glucose by the help of the process known as photosynthesis.

The second picture here is caterpillar who is a primary producer feeding on the plant for its energy needs.

The third picture is a bird who is secondary consumer that is eating the caterpillar for its energy needs.

This shows how the energy travels from the sun→producers→ primary consumer→secondary consumers.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
