The ecological succession that occurs in a lava field is as follows:
- Moss and lichen arrive by birds to barren lava field.
- Soil is created.
- Fountain grass grows.
- Monkeypod trees grow.
<h3>What is ecological succession?</h3>
Ecological succession refers to the series of changes that occur in a habitat gradually with new species replacing existing species or a barren habitat until the environment becomes more complex.
A lava field is a barren field where there are no species
The ecological succession that occurs in a lava field is as follows:
Moss and lichen arrive by birds to barren lava field; Soil is created; Fountain grass grows; Monkeypod trees grow.

Answer:
There are two possible answers: Deep-sea vents provided the energy needed for the first organic compounds to form OR self-replicating RNA molecules passed on genetic information.
Explanation:
The reason for the first answer is due to the hypothesis that indicates that life (organic molecules) arose from inorganic molecules synthesized from the amino acids in those energy vents. This is called the metabolism first hypothesis. The Miller-Urey Experiment provided evidence that organisms could rise from inorganic molecules (they simulated under the conditions you would see on early Earth). The second hypothesis is the RNA World hypothesis (second answer) which suggests that the formation of RNA that could replicate (possible due to mutation or evolution), led to life that could preserve its genetic integrity through replication (greater stability to the organism) and create lipid bi-layer membranes/other organelles. Some scientists support the Metabolism First Hypothesis, while others are skeptical (this goes for the RNA World Hypothesis as well). However, the RNA World Hypothesis is for more reasonable in the fact that its main point is the fact that RNA molecules were able to replicate and maintain genetic stability despite early Earth conditions. Although either hypothesis could explain why all organisms share the same genetic code, the RNA World Hypothesis better explains the universality of DNA/RNA of genes that we see today.
