In what era had small simple marine organisms?
Small simple marine organisms have existed since the Precambrian era, which ranges from about 4.6 billion years ago to around 541 million years ago. These organisms were some of the earliest forms of life on Earth and played a crucial role in shaping the planet's early ecosystems.
What is the difference between marine algae and marine plants?
Marine algae are simple, photosynthetic organisms that lack true roots, stems, and leaves, such as seaweed. Marine plants are more complex, multicellular organisms with roots, stems, and leaves, such as seagrasses. While both contribute to marine ecosystems, marine algae are typically found in intertidal and subtidal zones, while marine plants are found in shallow coastal waters.
Which evolved first - organisms with complex body structures or those with simple body structures?
Complex organisms evolved from simple organisms, so simple organisms evolved first.
When did the first marine plants appear on earth?
the first plants appeared about 3000 years ago. the first plant was algae.
What do complex organisms and simple organisms have in common?
They're both organisms, right?

What ecosystems include?
An ecosystem means the surrounding in which we liv with all other living organisms...in simple context to say is tat its our surrounding or Environment.
What eats crill?
Krill is important in the marine food chain and is eaten by a variety of animals, including whales, penguins, seals, fish, and seabirds. They are a crucial food source for many marine predators in ecosystems around the world.

Is a marine flat worm a parasite?
maybe, maybe not The world may never know
Which statement best describes ecosystems on Earth?
Apex question test which best describes the first organisms on Earth is simple prokaryotes.
When did the first marine plants appear on earth?
the first plants appeared about 3000 years ago. the first plant was algae.
What are two living things in parts of an ecosystems?
It is as simple as this.ANIMALSPLANTS
Why is there a gap of time between the evolution of algae and trilobites?
There isn't, of course, a gap in time. There are, however, very few fossils intermediate between simple stromatolites (the first more or less multicellular organisms) and the first complex organisms found just before the Cambrian Explosion. This gap most likely exists because while predation already existed (organisms consuming other organisms), no organisms had yet developed an internal or external skeleton that could have been preserved at death. The very few organisms from that era that were preserved despite of this, were preserved in the form of molds and casts.
Can one organism live without interacting with other organisms Why?
No for the simple reason that, on Earth, there are no ecosystems with only one single organism present. Perhaps in some hypothetical scenario an organism may survive without other organisms present, but it would be an artificially created/maintained environment.
What does Organism mean in science term mean?
In science, an organism is any individual living being that exhibits characteristics of life, such as growth, reproduction, and response to stimuli. Organisms can be unicellular (like bacteria) or multicellular (like plants and animals), and they are the building blocks of all ecosystems. Organisms can range in complexity from simple single-celled organisms to highly specialized and complex organisms like humans.
