The position of an organism along a food chain is known as its
locus
location
trophic level
microcosm

The correct answer is C. Trophic level

Explanation:

In biology, a food chain refers to a network that describes the relationship between the organisms in terms of food or the way organisms eat other and can be eaten. Because of this food chain are organized according to different levels that include producer organisms such as plants, herbivore animals such as rabbits, predators that eat other animals such as eagles and decomposers such as certain worms or bacteria. Each of these levels is known as a trophic level and describe the position of each type of organism in the food chain. Additionally, food chain guarantees balance in the ecosystems as it controls the population of species. Thus, the position in the food chain refers to a trophic level.

The cells adapted by modifying their shapes.

Explanation:

The larger the cell, the smaller the surface / volume ratio. This can be a problem because it causes the cell to have difficulty in absorbing nutrients, in addition to having difficulties in releasing substances that are not relevant inside. To circumvent these difficulties and have a good functioning, many large cells adapt by modifying their shapes to increase their surface. In this way many large cells are presented with a thin and elongated shape, others create several appendages on their surface.
