I think the answer should be:<span>D) Small Fish and other Aquatic Species

In food pyramid, the biomass will be much lower in the higher level. In general, every level will have lower of mass/energy compared to the level below. Then, the greatest biomass should be found in the producer class. High-level consumer like bird or mammals should have the lowest mass.
But it was inverted in aquatic, producer become the lowest mass so phytoplankton and zooplankton must be lowest. You should be able to exclude option A and C so it is either option B or D. Since B has zooplankton, I prefer to choose D

Answer:
Explanation:
Oxygen gas and water must be present for iron to rust.
A region of the metal’s surface serves as the anode, where oxidation
occurs:
Fe(s) → Fe²⁺ (aq) + 2 e⁻
The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:
O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)
The overall redox reaction is:
2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)
The Fe²⁺ ions formed at the anode are further oxidized by oxygen:
4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)
This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.
Cohesion is the connection made between identical molecules while adhesion is the connection between different ones
Answer:
<h3>Habitat isolation is responsible for causing speciation between the two species of garter snakes.</h3>
Explanation:
- Habitat isolation is a type of isolation in which two species are barred from mating or interbreeding due to the presence of physical barriers between them such as mountains, rivers, etc.
- Habitat isolation only can happen if two species occupy different habitats.
- Example- Gryllus pennsylvanicus prefer to live in those soil which has less water content like in sandy soil & Grylus firmus prefers to live in soil rich in water moisture i.e. loamy soil
Answer:
High to low concentration is how water flows
