Answer:
A
Explanation:
the sun gives energy to the grass to grow then the animal eats the grass and gets the energy and then the decomposer or mushroom will break it down for food.
Answer: a.
b.
Explanation:-
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
The balanced chemical equation is:
Here, is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
And, is gaining a proton, thus it is considered as a base and after gaining a proton, it forms which is a conjugate acid.
The dissociation constant is given by:

Answer:
Carbon is a highly covalent element due to the presence of four valence electrons in its outermost shell. This helps it bond covalently with other elements in various ways.
Carbon is known to be the backbone for most compounds. The carbon backbone vary in length and in the mode of bonding such as having the ability to from straight, branched, rings, double or triple bond which contibutes to the diversity and complexity of organic molecules.
Answer:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force
His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them
