Which is biotic?
a. wind
b. iron gate
c. sunlight
d. dead leaf

Biotic refers to the living organisms that live in that ecosystem. On the other hand, abiotic refers to the non livng organisms that are present around the living organisms in that ecosystem. They can also affect how the living organisms live. Examples of this are sunlight, moon, moisture. Wind, iron gate and sunlight are abiotic components. A dead leaf however, is biotic. Even if it is dead, decomposing bacteria will grow in the plant. And bacteria are living things. The answer is letter D.

The correct answer is a dead leaf.

Biotic factors are the living organism that made up the ecosystem. The biotic components in an ecosystem include microorganisms, plants, and animals.

Further Explanation

Also, the ecosystem is made of abiotic components such as temperature, sunlight, chemicals in the soil and clouds.

Humans and microorganisms, including all living organisms, are regarded as biotic factors.  

However, there 3 main categories of biotic factors and these include:

Autotrophs are producers, Examples of organisms that are classified as Autotrophs are algae and most green plant. They can produce their product through a process known as photosynthesis.

Heterotrophs are consumers, examples of organisms that are classified as heterotrophs in the ecosystem include, bacteria, fungi, herbivores (cow, sheep), and omnivores (humans, rats, birds, etc). The heterotrophs made up approximately 95% of the living organism within the ecosystem.

Detritivores are also classified as consumers, but they categorized differently because of what they eat. Within the ecosystem, the Detritivores are also known as decomposers because they feed on dead organisms. Examples of organisms that feed on dead organisms include earthworm, millipedes, sea stars and many more.

However, the three categories of abiotic or non-living factors in the ecosystem include:
