In the context of ecological succession, one of the first autotrophs to appear is typically the aquatic plant (option 2). Aquatic plants are often pioneers in newly formed or disturbed aquatic environments, as they can quickly establish themselves and begin photosynthesis, contributing to the ecosystem's energy source. Frogs, trees, and fish are generally higher trophic levels and depend on the presence of autotrophs like aquatic plants for their survival.
they are the last organisms to appear.

During the Archaean Eon
Autotrophs are believed to have appeared around 3.5 billion years ago during the Archean Eon. These primitive organisms were the first to harness energy from sunlight to produce organic compounds through photosynthesis.
No. Just number of chromosomes cannot indicate whether the organism is a plant or an animal.
primary succession
Photosynthetic autotrophs, such as cyanobacteria, are believed to have appeared on Earth around 2.7 billion years ago. These early organisms were instrumental in producing oxygen through photosynthesis, leading to the Great Oxidation Event that transformed Earth's atmosphere.
Lichens are the first organisms to appear in primary succession because they are able to colonize bare rock surfaces and begin breaking it down into soil through their ability to produce acids that break down minerals. Lichens are also able to survive in harsh environmental conditions, making them well-suited to establish themselves as pioneer species in the initial stages of primary succession.
The answer is Salinty
Read your science book chapter . It is on the first page.
Multicellular organisms first appeared during the Vendian period.
Without knowing what the outside influence is, it's not known how it will change the appearance of an organism. There are many different influences which could possibly change the appearance of an organism, depending on what the organism is.
