If iodine solution reacts with starch, it will change color into black.
Since the yellow-orange iodine solution stayed the same <span>color when it was put on the apple, it can be concluded that there is no starch in the apple. On the other case, the black color of the potato suggests that there is a great amount of starch in the potato. Anyway, this does not mean that there is no starch in the apple at all. As fruits ripen, starch slowly changes to sugar. Iodine cannot react with sugar, so the black color in the apple is missing.</span>

Determine whether each phrase describes a community, ecosystem, habitat, or population.
Yuri [45]

Answer:

A herd of bison - population

Frogs, insects, and birds living near a pond - community

The plants, animals, water, and soil of a forest - ecosystem

The kelp forest where sea otters live - habitat

All the hummingbirds that live in your state - population

Fish, eels, and lobsters living in a coral reef - community

A dying tree with holes that animals live in - habitat

Wetland plants, animals, and marshes - ecosystem

Explanation:

In ecology, the interaction of organisms are classified into categories including population, community, ecosystem etc.

A population in ecology consists of all the members of a particular species that inhabits a particular location. Based on the wide range of examples given in the question, a herd of bison and all the hummingbirds living in my state are examples of a population because they consists of organims of same species (bison and hummingbirds) living in a particular habitat.

A community, as opposed to population consists of organims of different species that share the same location as habitat. According to the question, Frogs, insects, and birds living near a pond and Fish, eels, and lobsters living in a coral reef are examples that represents a community because they contain organims of different species found living in a common habitat.

An ecosystem is the interaction between the biotic components (living) of a community with one another and also with the abiotic components (non-living). Based on the question, The plants, animals, water, and soil of a forest and Wetland plants, animals, and marshes represents an example of ecosystem because they contain living and non-living components interacting together. The living components in the first and second examples are plants, animals while abiotic components are water, soil and marsh.

Habitat refers to the physical location where the population or community of organisms lives. In this question, the kelp forest where sea otters live and a dying tree with holes that animals live in describes habitats of organisms.
