(3) It involves interactions between biotic and abiotic
factors.
Explanation:
An ecosystem involves the interaction between biotic and abiotic factors.
The biotic factors are the living components of the ecosystem. The abiotic factors are the non-living components.
An ecosystem is made up the interaction between living organisms and their environments.
- Ecosystem are combination of the community of lives and the environment.
- The environment contains the non-living abiotic components.
- The organisms are the living components.
- All of this merges together to form of the ecosystem.

This question is more for Biology than Chemistry, but the role of producers is to make energy (food) to be consumed. In a pyramid diagram, the producers would be at the bottom. Now going up the pyramid, the primary conumers are the first to consume producers and obtain energy from them. As you go up the pyramid, the secondary consumers will consume the primary consumers as a way to obtain energy, and the same goes for tertiary consumers towards secondaries.
As you go up the energy pyramid, you will notice a trend that there is less energy being obtained from each consumer. In other words, the producers will ALWAYS have more energy than the tertiary consumers.
I hope this answers your question.

Answer:
Rutherford's theory laid the foundation upon which Bohr's model is founded. Rutherford established the fact that at the center of the atom, there is a nucleus whose radius is smaller than the radius of the atom. This nucleus is positively charged and most of the mass of the atom is concentrated there. Electrons move round this nucleus in orbits.
The experimental evidences of the Bohr's model shows that Rutherford's model was fundamentally correct. However, Bohr's model introduced the idea of quantization of the energy of electrons in an atom. The model went further to explain the spectra lines of the hydrogen atom.
