A. Most people thought that trillium was not getting enough sunlight in the forest.
Explanation – Scientists used to believe that the population of trillium decreased because there were not enough sunlight to reach these plants. Later, it was found that deer used to eat the flowers of trillium plant that led to the decrease of its population.
The seed of the trillium plant is very nutritious and hence consumed by the deer. Because of this, trilliums were found to be unlikely to recolonize local areas on their own.
Answer:
Q1: C. salinity Q2: density Q3: B. densest, least dense Q4: C. closest to the surface
Explanation:
Q1: The term "salinity" refers to the concentrations of salts in water or soils. Q2: when the amount of salt in the water increase which usually gathers mostly at the shallow top of the ocean which is where the warm shallow water gathers, when the warm water has enough salt in it, it sinks to a deeper location causing its density to heighten and that's also what makes it cold. Q3: When layers form in the ocean, the water containing the most dissolved salt tends to form the bottom layer. The water having the least amount of salt is usually on top, because it is the least dense. As more solids are dissolved in water, the water becomes more dense. Q4: Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface. I really need brainliest please do so.
