When chemical, biological and ecological changes occur the plants start to die and decompose, fish die, carbon dioxide is released. Hence the correct option is B.
Ecological change also known as environmental change is defined as the alteration or disturbance of the environment usually caused by human impacts and natural ecological processes. Environmental changes include various factors, such as natural disasters, human interference, or animal interactions.
The ecological changes are affected by the following reasons such as habitat change, climate change, invasive species, overexploitation, and pollution. When chemical, biological and ecological changes occur the plants start to die in the pond and start to decompose, fish die, carbon dioxide is released.
Hence the correct option is B.

Answer:
Genetic variation
Explanation:
Darwin studied that different populations of finches on Galapagos island that are descended from the same species. Some species are evolved to eat nuts and large seed, some eat small seeds and some feed on insects and nectar.
So genetic variation occurred in different populations of finches which enabled them to bring changes in their beak according to the food resource they have chosen to feed on.
So in Darwin's finches, genetic variation leads to new species which is a type of natural selection. Therefore subset of finches that can feed on large seeds and small seeds is an example of genetic variation.

1. The probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 is 0.284.
2. The probability that a person who is older than 35 years has a hemoglobin level of 9 and above is 0.531.
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Given
Let the number of person who is older than 35 years has a hemoglobin level between 9 and 11 be x.
From the given table it is clear that the total number of person who is older than 35 years is 162.
76+x+40 = 162
116+x = 162
x = 46
The number of person who is older than 35 years has a hemoglobin level between 9 and 11 is 46.
1.The probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 is
P = 46/162 = 0.62
The probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 is 0.284.
Person who is older than 35 years has a hemoglobin level of 9 and above is 40+46 = 86
The probability that a person who is older than 35 years has a hemoglobin level of 9 and above is
P = 82/162 = 0.531
The probability that a person who is older than 35 years has a hemoglobin level of 9 and above is 0.531.

Explanation:
Animals get energy from food. Plant related food takes the sun to grow, and other prey may get energy from plants which uses the sun to grow. If you have any questions, don't hesitate to ask!
