What would happen if there were no abiotic factors in an ecosystem?
Brums [2.3K]

Answer:

Plants would be unable to grow and produce oxygen for the animals.

Explanation:

Sunlight, which supports plants, is considered an abiotic factor. If there were no sunlight, plants wouldn't be able to grow, which means no oxygen for many living things found in that specific ecosystem. In other words, that ecosystem would become uninhabitable.

Please help at soon as possible!
Butoxors [25]
For starters, the left image is a plant cell and the right image is an animal cell.

The black dots in both images would be drawn to the nucleus. All cells have nuclei. The black oval in the right image would be drawn to the cell membrane. Only animal cells have these. The rectangle with a gap would be drawn to the cell wall. Only plant cells have cell walls. The space surrounding the nucleus in both cells would be drawn to cytoplasm. All cells have cytoplasm. The dotted circles would be drawn to chloroplast. Only plant cells have these.

Hope I could help!

What is still lacking in the hypothesis of an asteroid impact as the cause of the end-cretaceous mass extinction?
Doss [256]

A convincing explanation of why some lineages survived while others vanished is still lacking in the hypothesis of an asteroid impact as the cause of the end-cretaceous mass extinction.

<h3>What is an asteroid?</h3>

One of the smaller planets in the inner Solar System is an asteroid. Asteroids are metallic or rocky bodies without an atmosphere, ranging in size from 1-meter pebbles to a dwarf planet with a diameter of over 1000 km.

The majority of the one million or more known asteroids are concentrated in the main asteroid belt, which is 2 to 4 AU from the Sun and between the orbits of Mars and Jupiter. The three categories of asteroids that are typically recognized are C-type, M-type, and S-type.

These were given their names and are frequently associated with, respectively, carbonaceous, metallic, and silicaceous compositions. The largest asteroid, Ceres, has a diameter of over 1,000 km (600 mi), making it a dwarf planet.
