2. Objective: Learn How Habitat and Niche Differ Key Words: Niche, Habitat, Bullfrog
A mature bullfrog catches insects, worms, spiders, small fish, or even mice. Predators such as herons, raccoons, and snakes prey on bullfrogs.
Bullfrogs spend their lives in or near the water of ponds, lakes, and slow-moving streams. A bullfrog’s body temperature varies with that of the surrounding water and air. As winter approaches, bullfrogs burrow into the mud of pond or stream bottoms to hibernate.
Female bullfrogs lay their eggs in water during the warmer months of the year. The young frogs, called tadpoles live in the water until their legs and lungs develop.

Basketball positions in the offensive zone
One guard, two forwards, and two centers or two guards, two forwards, and one center were used.
Point guard: organizes the team's offense by controlling the ball.
Shooting guard: creates a high volume of shots on offense.
Small forward: responsible for scoring points via dribble penetration.
Power forward: plays offensively often with their back to the basket; on defense, plays under the basket.
Center: uses height and size to score (on offense), to protect the basket closely (on defense), or to rebound.
