Answer the following question given this paragraph: All organisms have the ability to grow and reproduce. To grow and reproduce, organisms must get materials and energy from the environment. Plants obtain their energy from the sun through photosynthesis , whereas animals obtain their energy from other organisms. Either way, these plants and animals, as well as the bacteria and fungi, are constantly interacting with other species as well as the non-living parts of their ecosystem. Q: Plants obtain their energy from the sun through photosynthesis , what do animals obtain their energy from? Choices: - tissues - proteins - ultraviolet rays - organisms A:
(A).
organisms

Answer the following question given this paragraph: Hearing is the ability to sense sound waves, and the ear is the organ that senses sound. Sound waves enter the auditory canal and travel to the eardrum (see Figure below ). They strike the eardrum and make it vibrate. The vibrations then travel through several other structures inside the ear and reach the cochlea. The cochlea is a coiled tube filled with liquid. The liquid moves in response to the vibrations, causing tiny hair cells lining the cochlea to bend. In response, the hair cells send nerve impulses to the auditory nerve , which carries the impulses to the brain. The brain interprets the impulses and "tells" us what we are hearing. Q: What is the organ that senses sound? Choices: - nose - eye - skin - ear A:
ear
