However, in the absence of wolves, the prey populations increased disproportionately, causing a decline in the population of plant species. This decline disrupted the ecosystem. Following a study of the wolves’ impact, ecologists regarded wolves as the _________of the ecosystem, as their absence caused a __________ effect on the ecosystem.
For the first blank here are the choices:


- keystone species


-prey species


- diverse species

Keystone species for the first blank. This is because keystone species are what holds an ecosystem together. 

direct impact because the removal of a keystone species is neither beneficial or a domino effect. if the entire ecosystem relies on that one species, then the niches of all the animals in that ecosystem will be directly affected.

Answer:

A) Light pollution both attracts and repels migratory birds

In addition to the many hazards that exist in urban areas, cities typically lack the food resources and cover that birds need during migration or when raising their young. ... Darkening skies at night during migration season makes it easier for birds to navigate.

Explanation:

Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by availability of food. It occurs mainly in the northern hemisphere, where birds are funneled on to specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea.

In osmosis, water molecules move with the concentration gradient, therefore no energy is used. This is an example of:
olganol [36]

Answer:

The correct option is A. Inside of cell has more salt

Explanation:

When there will be more solute inside the cell than outside of the cell, then a concentration gradient will develop due to this uneven distribution. Water will move inside of the cell through a process known as osmosis. As the water molecules are moving along the concentration gradient, no energy will be used during this process.

The mechanism of osmosis is very essential in maintaining the turgidity of a cell.
