Lion. What kind of organism is it? Prokaryote, eurkaryote? What is its ecological role? Is it a producer? Is it a herbivore? Is it a predator?

Would be great to add a Primary Source to your answer.

Need to find 3 Primary Articles about the Lions Mane. Need to be in the last 25 years. How they adapt to the wild etc..

1. The lob in tennis is an effective tactic when your opponent is near the net. It consists of lofting the ball over his head, forcing him to move quickly away from the net (see the drawing). Suppose that you loft the ball with an initial speed of v = 14.5 m/s, at an angle of θ = 53.5° above the horizontal. At this instant your opponent is 10.0 m away from the ball. He begins moving away from you 0.30 s later, hoping to reach the ball and hit it back at the moment that it is 2.10 m above its launch point. With what minimum average speed must he move? (Ignore the fact that he can stretch, so that his racket can reach the ball before he does.)

2. From the top of a tall building, a gun is fired. The bullet leaves the gun at a speed of 340 m/s, parallel to the ground. As the drawing shows, the bullet puts a hole in a window of another building and hits the wall that faces the window. (y = 0.58 m, and x = 6.3 m.) Using the data in the drawing, determine the distances D and H, which locate the point where the gun was fired. Assume that the bullet does not slow down as it passes through the window.

3. A cable is lifting a construction worker and a crate, as the drawing shows. The weights of the worker and crate are 907 and 1490 N, respectively. The acceleration of the cable is 0.620 m/s2, upward.

A 18.0 kg sled is being pulled across a horizontal surface at a constant velocity. The pulling force has a magnitude of 79.0 N and is directed at an angle of 30.0° above the horizontal. Determine the coefficient of kinetic friction.

A hot-air balloon is rising upward with a constant speed of 2.45 m/s. When the balloon is 2.80 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground?

A woman stands on a scale in a moving elevator. Her mass is 54.0 kg, and the combined mass of the elevator and scale is an additional 815 kg. Starting from rest, the elevator accelerates upward. During the acceleration, the hoisting cable applies a force of 9380 N. What does the scale read during the acceleration?

A jetliner, traveling northward, is landing with a speed of 72 m/s. Once the jet touches down, it has 715 m of runway in which to reduce its speed to 6.0 m/s. Compute the average acceleration (magnitude and direction) of the plane during landing (take the positive direction to be northward).
