Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula.
With the rise of the sun, the remaining material began to clump together. Small particles drew together, bound by the force of gravity, into larger particles. The solar wind swept away lighter elements, such as hydrogen and helium, from the closer regions, leaving only heavy, rocky materials to create terrestrial worlds. But farther away, the solar winds had less impact on lighter elements, allowing them to coalesce into gas giants. In this way, asteroids, comets, planets and moons were created.
Autotrophs and Heterotrophs benefit each other by providing raw materials for various life processes ,directly or indirectly .
Explanation:
- Autotrophs can prepare their own food by using sunlight .This is not possible for Heterotrophs. Heterotrophs obtain their food from Autotrophs.
- Heterotrophs Feed on Plants and helps them in Pollination and Seed dispersal.
- Autotrophs Carry out photosynthesis and produce oxygen which is taken up by heterotrophs for respiration. Heterotrophs in turn, give out Carbon dioxide which is used up by autotrophs.
- Heterotrophs like detrivores and decomposers obtain there food from decaying plant parts and thus break down the nutrient which is then made available to plants.
The answer is; C
It is a woody plant with a flexible stem that can grow extremely long. Its stem cannot stand vertically on its own hence uses other trees for support and climbs up the canopy for good sunlight. They are common plants in rainforests and play a significant role in the ecosystems. They provide support for weaker trees from strong winds and provide bridges for arboreal animals such as monkeys.
Answer:
aka Ethenone
Explanation:
Ethenone is an organic compound made out of the elements Carbon, Hydrogen, and Oxygen. It is an example of a covalent molecule. The Hydrogens are single bonded to the carbon and then the carbons and oxygen are double-bonded to each other. Additionally, because there are 2 Hydrogens and 1 Oxygen the ratio is 2:1, as stated in the question.
