Answer:

Trophic level

Consumer

Producer

Explanation:

All living organisms require energy for their life processes, which they obtain by taken in food. In an ecosystem, this food is derived when organisms feed on each other. This process that eventually leads to a flow of energy within organisms is called FOOD CHAIN.

A food chain or food web always begins with a unique set of organisms called PRODUCERS. Producers are autotrophs capable of harvesting light energy from the sun and use it to produce their food (chemical) in a process called PHOTOSYNTHESIS. Other organisms called HETEROTROPHS feed on these producers to derive energy. In ecology, they are called CONSUMERS. Other consumers feed on the previous ones also to get energy.

Hence, each step of the food chain is occupied by organisms that obtain and store energy by feeding on another organism. This step is called TROPHIC LEVEL.

In a nutshell, a PRODUCER (usually plants) starts the food chain/web due to its photosynthetic ability. This producer gets eaten by an organism called CONSUMER and in the process, the energy and nutrient stored in the producers flows to the consumer. Another consumers feeds on the previous one and the energy keeps flowing. Each step of the food chain occupied by an organism that stores and transfers this energy is called TROPHIC LEVEL.

Choose the structures that most directly provide nutrients and remove wastes from osteocytes in compact bone.
Ber [7]
I had to look for the missing options of this question and here is my answer:

Osteocyte is the term that describes the cells of the bone. These cells are formed in the mesenchyme. Once the bone matures, the processes then take place inside the Lacunae and the Canaliculi, respectively. Therefore, we can say that the structure that allows the provision of nutrients and removal of wastes from osteocytes would be the canaliculi.
