<h2>Answer:</h2>
The correct option is B which is plants.
<h3>Explanation:</h3>
Food chain contains:
- Producers: Organisms that produce food for their own and other animals. They convert simpler compounds into complex compounds.
- Consumers: They utilize the food made by the consumers. There primary, secondary and tertiary consumers.
- Decomposers: They convert complex organic compounds into simpler one.
So plants are autotrophic and they are the producers in food chain.
Hence Earth's food chain starts with plants.
Evidence consists facts intended for use in support of a conclusion.
Why Evidence is important?
Evidence based research is the use of prior research in a systematic and transparent way to inform a new study so that it is answering questions that matter in a valid , efficient and accessible manner.
Evidence can come from the piece of genetic material or trace chemical to dental history or fingerprint.

Answer:
Active transport is what i'm going to go with because it makes the most sense and matches the statements
Explanation:
So therefore Active transport is your answer. (tell me if i'm wrong)
The two enzymes that help in the generation of NADPH which is essential for fatty acid synthesis are the Glucose-6-phosphate-dehydrogenase(G6PDH) and the Malic enzyme.
NADPH is predominantly produced by the pentose phosphate pathway, either directly by the malic enzyme as it oxidized malate to pyruvate or indirectly through the glucose-6-phosphate dehydrogenase.
NADP+ is used to make NADPH. The pentose phosphate pathway, which is catalyzed in the first stage by glucose-6-phosphate dehydrogenase (G6PDH), is the main source of NADPH in mammals and other non-photosynthetic organisms.
From glucose, the pentose phosphate pathway also generates pentose, a crucial component of NAD(P)H.
However, the Entner-Doudoroff route is also used by some bacteria, and NADPH generation is unaffected.

Answer: changed by molecular oxygen
Explanation:
Biologically induced molecular oxygen (dioxygen, O2) started to accumulate in Earth's atmosphere and changed Earth's atmosphere from a weakly reducing atmosphere to an oxidizing atmosphere.
