I don’t know if this is right but I thing It’s B
The answer is A cause gas clouds hold elements in it
Sun⇒ Phytoplankton (Producer)⇒ Zooplankton (Primary consumer)⇒ Fish (Secondary consumer)⇒ Bear (Tertiary consumer).
- A food chain is a sequence of transfer of food and energy when one organism is consumed by another organism.
- A food chain is always unidirectional sequence.
- In the provided food chain the sun is the source of energy required for the preparation of food by the phytoplankton that is an aquatic autotroph which will prepare its food by the process of photosynthesis.
- The phytoplankton being producer of biomass is consumed by the zooplankton that is the primary consumer than the zooplankton will be consumed by the fish that is the secondary consumer and carnivore by origin and finally the fish will be consumed by the bear that is also carnivore and is tertiary consumer.

Answer:
2.5×10⁶ s
Explanation:
From the question given above, the following data were obtained:
Rate constant (K) = 2.8×10¯⁷ s¯¹
Half-life (t½) =?
The half-life of a first order reaction is given by:
Half-life (t½) = 0.693 / Rate constant (K)
t½ = 0.693 / K
With the above formula, we can obtain the half-life of the reaction as follow:
Rate constant (K) = 2.8×10¯⁷ s¯¹
Half-life (t½) =?
t½ = 0.693 / K
t½ = 0.693 / 2.8×10¯⁷
t½ = 2.5×10⁶ s
Therefore, the half-life of the reaction is 2.5×10⁶ s
The weakness of the rutherford model of the atom that bohr addressed is that
- The energy of the atom is quantized and
- The atom does not lose energy as the electon rotates about the nucleus
<h3>What is Rutherford model of the atom?</h3>
The Rutherford model of the atom proposed by Ernest Rutherford in 1911 shows that the atom is much hollow space with its mass concentrated at the center being surrounded by electrons. It is the planetary model.
<h3>What is the Bohr model of the atom?</h3>
The Bohr model of the atom proposed by Neils Bohr in 1913 suggests that
- the energy of an atom is quantized and
- that it does not lose energy as the electron rotates about the nucleus.
<h3>What was the weakness of the rutherford model of the atom that bohr addressed?</h3>
The weakness of the rutherford model of the atom that bohr addressed is that
- The energy of the atom is quantized and
