Answer:
The food chain describes who eats whom in the wild. Every living thing—from one-celled algaeto giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.
For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.
Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
Answer:
The continental plate is the location where volcanoes form when the convection in the asthenosphere creates a column of material that rises until it reaches the crust.
Explanation:
Volcanoes form at the edges of Earth’s tectonic plates. When the continental plate moves over the oceanic plate, it causes the oceanic plate to descend into the mantle where some of it melts, and the molten material moves into the mantle above the plate and causes the mantle to melt.
This liquid rock, called magma, rises to the surface because it is less dense then the surrounding rock, a volcano forms when the magma reaches the surface of the Earth at the continental plate.

Answer:
1. reducing soil erosion,
2.Controlling runoff water
Explanation:
Contour farming mitigates the impacts of floods, storms and landslides on the crops by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality and composition
