Answer:
The food chain showing seven organisms can be drawn as follows:
Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers
The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.
An energy pyramid for three of the organisms can be shown as follows:
mice (10 kilocalories)
↑
Grasshoppers (100 kilocalories)
↑
Plants ( 1000 kilocalories)
As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.

Explanation:
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
Lymph traveling from the left arm would enter the venous circulation via the thoracic duct.
<h3>
What is thoracic duct?</h3>
- The largest lymphatic channel in the body's lymphatic system is the thoracic duct, commonly known as van Hoorne's canal.
- Adults have an average length of 40 cm, and their abdominal origin is about 5 mm wide.
- The thoracic duct runs from the root of the neck to the twelfth thoracic vertebra.
- The thoracic duct enters the posterior mediastinum, remaining to the right of the vertebral column, by ascending via the diaphragm's aortic hiatus.
- At the T7 vertebral level, it runs posterior to the esophagus before crossing over to the left side of the thorax at the T5 vertebral level.
- The primary lymphatic channel for the return of chyle/lymph to the systemic venous system is the thoracic duct.
- It drains lymph from the left side of the face and neck, left hemithorax, left upper limb, and both lower limbs.

Answer:
B
Explanation:
Amount of energy decreases as it goes higher up the trophic levels.
