Each column is called a group.
<u>The elements in each group have the same number of electrons</u> in the outer orbital
Forest Food web consists of the producers, main consumers, secondary consumers, scavengers, and decomposers. Food web is the collection of the large number of food chains.
<h3>What are some examples of food webs?</h3>
Numerous food chains make up a food web. As animals seek food, a food chain only follows one way. As an example, a hawk consumes a snake following the consumption of a frog, a grasshopper, and grass. A food web illustrates the numerous relationships between plants and animals.
<h3>What are the different types of food web?</h3>
1. Primary consumers
2. Secondary consumers
3. Tertiary consumers
4. Decomposers or phytoremediators

Answer:
C₄H₁₂ + 7O₂ --> 4CO₂ + 6H₂O
Explanation:
Organic molecules react with O2 to create water and CO2 in combustion processes. C4H12 is an organic molecule that combines with O2 to create water and CO2 as shown in the reactions.
As a result, this is the sole reaction that obeys the general combustion equation.
