when viewing particles under a microscope, you note that they are constantly bouncing around. this is described as
Answers
The constant movement of particles when seen under a microscope is a very common observation known as Brownian motion.
All particles are made of atoms. Atoms are comprised of three components:
NeutronsProtonsElectronsthe first two comprise the core of an atom, surrounded by a cloud of electrons.
Though much too small to be seen without aid, these atoms do indeed possess mass and are capable of colliding with one another. Particles constantly collide with one another and are bounced in the opposing direction, over and over again. This is precisely what we observe under the microscope as particles bouncing around and is referred to as Brownian motion.

c. water fleas, diving beetles
d. heron, perch
e. one thing that could happen if all frogs suddenly died is that there would be an overpopulation of slugs, insects, and beetles. another thing that could happen would be that foxes would only rely on getting slugs for food so the slugs would soon go extinct and the plants would possibly over populate.

a. Producer: Land plants and tiny water plants.
a. Three consumers: Slug, insect, and newt.
b. Food chain with six levels: Land plants, insects, diving beetle, small, perch, and heron.
c. Small fish eat diving beetle and water fleas.
d. Heron and perch each small fish.
e. Food will decrease for foxes and herons in the food web.
a. Within the given food web, land plants and tiny water plants serve as the primary producers. They capture energy from the sun and convert it into usable energy through photosynthesis.
b. Moving along the food chain, the insects, such as caterpillars or grasshoppers, serve as a food source for other organisms.
c. The land plants provide energy to the insects, which in turn provide energy to the diving beetle. The diving beetle sustains the small perch, which is then consumed by the heron.
d. Heron and perch each small fish in the given food web. Perch and Heron are consumers of small fishes.
e. In the given food web, if there were a decrease in the population of small fish such as perch and water fleas, which are part of the diet of herons and small fish respectively, the herons and foxes would experience a decrease in their food supply. This would likely have an impact on the population dynamics and interactions within the food web, potentially leading to changes in the abundance and distribution of the organisms involved.
