The abiotic community of the ecosystem or the nonliving objects in the earth's biosphere influences the survival, growth and development of the organism. They provide basic mmaterials to support life by the biogeochemical processes which is composed of many biological and environmental cycles which profoundly has factored the intiation and continuation of life on earth. They also provide the basic materials to support life by the undergoing process which is also initiated by the living creatures or the biotic society of the ecosystem.

Answer: primary ecological succession
Explanation:
Primary ecological succession: This occurs when a certain or some organisms dominate an area that was uninhabited of life. This may happen after a natural disaster that leaves the land barren. The presence of these organisms on the barren land will help the soil occupied to gain nutrients which will eventually allow some other plants to grow on it. The growth of plants will later invite insects and insects may invite animals.
GPE = mgh (for objects close to earth where g can be considered to be constant) Where m is the mass, g is the acceleration due to gravity (which the question has told us to assume is 10ms^-2), and h is the height of the object.
Substituting the values in:
GPE = 70*10*10 = 7000J
Answer:
Explanation:
Hooke's law is represented by thee formula
F = ke where F is force in N and K is the spring constant.
Initial length of the spring = 34cm = 0.34 m
mass of 7.00kg hung
weight = mg = 7 × 9.8 = 68.6 N
Final length of the spring = 44.5 cm = 0.445 m
extension = final length - initial length = 0.445 m - 0.34 m = 0.105 m
a) F = Ke
K = F / e = 68.6 N /0.105 m = 653.33 N/m = 0.653 kN/m
b) F = 150 N
k = 653.33 N/m
F = ke
150 N / 653.33 N/m = e
e = 0.23 m
new length = 0.34 + 0.23= 0.57 m = 57 cm
