Answer
Correct Answer is C (10% of the plant's energy is transferred
Explanation:
Ecosystem
ecosystem is a community where large number of living organisms lives. These living organism are plants, trees, different types of animals, birds etc. These living organism depends on each other for their food.
Their are various levels in ecosystem like producer, primary consumer, secondary consumer and tertiary consumer.
producer like plants produce their food on their own. And primary consumers takes their food from producers.
According to 10% Rule of ecology only 10% energy is passed from one level to another.So 10% of the plant's energy is transferred
<span>Electric field is proportional to q/d^2, where q is the magnitude of the charge and d is the distance. Since all the given units are identical, we can just compare their relative magnitudes without calculating for the exact values.
A) 3/(0.4)^2 = 18.75
B) 1.5/(0.2)^2 = 37.5
C) 6/(0.4)^2 = 37.5
D) 3/(0.2)^2 = 75
Therefore, choice D has the largest electric field of all.

Answer:
Scalar quantity
Vector quantity
Explanation:
A scalar quantity is a quantity that is fully described by magnitude alone. Examples include; mass, temperature etc
A vector quantity is described by both magnitude and direction. E.g force, weight etc
gravity, inertia, friction, kinetic energy?
