please answe all four

Name: 18. In the northern Pacific Ocean sea otters feed on sea urchins and on starfish. sea urchins Teed on kelp and starfish feed on mussels. Beginning in the 1700s, sea otters were hunted for theirfur and driven nearly to extinction in some areas, resulting in trophic cascades in their communities. When the fur trade ended, sea otter numbers increased and their communities began to recover. One would expect that this recovery would result in...

ASAP please write a hypothesis about which seedlings "light"
or "no light" will grow taller one week after germination.
and please draw the graph
details needed thank you
ntroduction: Photosynthetic plants require light to make sugars in order to produce the energy to grow. Yet, when we think about plants needing light to grow, we do not intuitively understand how light affects the rate at which plants grow taller. Plants do exhibit positive phototropism, which means they grow towards light....
