Answer:
1. cerebellum
2. brainstem
3. cerebrum
4. cerebrum
5. brainstem
6. cerebrum
7. cerebellum
Explanation:
The cerebellum is a region of the brain located behind the top part of the brainstem, which coordinates voluntary movements (e.g., posture, balance, coordination, speech). The cerebellum is well known to regulate the balance of the body. The brainstem is a type of automatic control center that connects the cerebrum with the spinal cord. The pons represents a group of nerves that serve as connection between the cerebrum and cerebellum. The pons are located in the brainstem (between the midbrain and the medulla oblongata). The cerebrum is the largest part of the brain and can be divided into right and left hemispheres. These hemispheres communicate with each other by the corpus callosum.

Explanation:
The "light" attracts prey to the anglerfish.
Freshwater ecosystems, constituting a mere 1.8 percent of Earth's surface, are characterized by their biodiversity and the crucial ecosystem services they offer, including provision of drinking water, sanitation, and industrial uses. They house different zones due to varying abiotic factors like temperature and light penetration, with each zone inhabited by species adapted to these conditions. They are intrinsic to the well-being of terrestrial biomes, linked through various abiotic and biotic factors.
Freshwater ecosystems are of immense importance due to their rarity, diversity, and functionality. They encompass only 1.8 percent of the Earth's surface, including lakes, rivers, streams, and springs. These ecosystems are incredibly biodiverse, supporting a wide variety of species such as fish, amphibians, reptiles, insects, phytoplankton, fungi, and bacteria.
Humans are heavily reliant on these freshwater biomes as they provide indispensable ecosystem services. They supply fresh drinking water, assist in crop irrigation, provide sanitation facilities, recreation spaces, and serve various industrial purposes. Conservation of these freshwater ecosystems is crucial for the preservation of terrestrial biomes, as they are interlinked through abiotic and biotic factors.
Temperature, light penetration, and water movements are key abiotic factors influencing these ecosystems. The structural compositions of aquatic systems are largely shaped by density and temperature. Such factors delineate different zones within these systems, each housing organisms adapted to specific conditions.
