Answer:
Decomposers
Explanation:
Decomposers are organisms that gives the soil essential nutrients for new plants to grow.
These are micro-organisms that takes up dead and decaying organisms. They break and reduce them down into useful soil organic matter.
Organic matter are the remains of plants and animals that are very vital in the soil. They provide nutrients needed for plant growth.
Complex organic molecules are broken down into simple and useful ones which are needed for the growth of plants.
Earth has trees and other planets don't have as much life as Earth so they don't have trees and wild life growing in them.

Answer:
Rifle Momentum=7.77kg*m/s v'= 1.554 m/s
Explanation:
a) m1v1 + m2v2 = m1v1' + m2v2'
0+0 = 0.03*259 + P(rifle momentum)
solve for P
p= 7.77kg*m/s
b) 7.77= 5*v'
v'= 1.554 m/s
The answer to this is 1 kg.
You use this equation:
m2 = m1 (g - a) / [a + g u cos θ + g sin θ]
You plug in the given values:
m2 = 0.7 (9.81 - 0.2) / [0.2 + 9.81(0.20) cos 30 + 9.81 sin 30)
The result is
m2 = 1 kg
