Explanation:

Answer 2

The minnows is an abiotic factor in the ecosystem Hence option 3 is correct.

What is ecosystem?

Ecosystem is defined as a structural and functional area of ecology where living things engage in interactions with one another and their surroundings. Ecosystem function refers to a system's capacity to directly or indirectly satisfy human wants for goods and services. Ecosystem functions are thought of as a subset of ecological processes and ecosystem structures.

The non-living elements of an ecosystem known as abiotic variables have an impact on their surroundings. Examples include temperature, light, and water in a terrestrial setting. Ocean currents and salinity are examples of abiotic components in a marine ecosystem.

Thus, the minnows is an abiotic factor in the ecosystem Hence option 3 is correct.

2. Temperate deciduous
3. Marine
4. Taiga
5. Tundra

Pls don't completely rely on it, this is my best guess and it's probably right except with Marine life and temperature deciduous. 70% I feel like it would temperate then marine. But check with urself again. Hope this helped..

What geometric shape is the carbon dioxide molecule? The Lewis structure for CO2 contains two double bonds.

Answers

Answer: Linear

Explaination: The central atom of a carbon dioxide molecule is carbon. Carbon is tetravalent which just means it has 4 valence electrons. Because the valence shell isn’t full, the carbon atom can bond with other atoms creating a total of 4 bonds. This then allows the carbon to double bond with 2 oxygen atoms. Now, the atoms in the CO2 molecule Don’t share the electrons evenly because of atomic number or proton count. Because oxygen has an atomic number of 6, carbon has an atomic number of 4, and opposites attract (referring to the positivity of the nucleus and the negativity of the shared electrons), the oxygen atoms will have a slightly negative charge (-) and the oxygen will have a slightly positive charge (+ ). Therefore, the slightly negative oxygen atoms repel creating that linear shape.
