Explanation:

The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.

• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.
• Biotic factors are all the living components in the ecosystem.  

Biotic and abiotic factors influence the survival and reproduction of living beings. They are related and in constant interaction. If one of these components is removed, the whole ecosystem will change because its equilibrium has been altered.  

Every abiotic component influence organisms and their survival and reproductive rates.

A few examples of the abiotic factors are solar light, minerals, water, air, gases, soil, and humidity.

Examples of biotic factors are plants, animals, insects, microorganisms, etc.

The biotic factors of the provided list are:

• People, which is a group of individuals composed of cells -which is the basic unit of life-. They grow, reproduce and survive.

• Grass, as one or many species of vegetables that are also multicellular. They grow, reproduce, and survive.

The abiotic factors are:

• Rocks, which are non-living things composed mainly of minerals

• Tent, which is also a non-living thing, is artificially made by humans.

In my opinion, the wooden kayak is a gray zone, meaning that it might be confusing. A kayak is an abiotic element with no life and is built by men. But it is constructed of wood. The wood originates in trees that are living beings, they are composed of cells, and they used to be alive. However, when talking about the kayak wood, we are referring to dead tissue. It is not alive anymore. Its cells are dead so, their whole system is not working. It is now composed of minerals and other elements with no life, and it has been modified and processed to build the kayak.

So my opinion is that the wooden kayak is an abiotic factor.
