1.) What is an organism’s niche? a.) the physical environment of the organism
b.) the role that an organism plays in the environment
c.) the traits that increase an organism’s survival
d.) the competitors and predators of the organism

2.) Which describes the habitat of a frog?
a.) color for camouflage
b.) prey for snakes
c.) eats insects
d.) marshes and ponds

3.) Elephants shape their environment in many ways. They can change a forest to a grassy field or dig a hole that might become a pond. They clear large amounts of vegetation, which removes habitats for some organisms but makes the area inviting for other organisms. Which best describes possible interactions of elephants with the surrounding ecosystem?
a.) positive
b.) negative
c.) neither positive nor negative
d.) both positive and negative

1.b.) the role that an organism plays in the environment

2. d.) marshes and ponds

3.d.) both positive and negative

D. Marshes and ponds

Elephants shape their environment in many ways. They can change a forest to a grassy field or dig a hole that might become a pond. They clear large amounts of vegetation, which removes habitats for some organisms but makes the area inviting for other organisms. Which best describes possible interactions of elephants with the surrounding ecosystem?

D. Both positive and negative

im gonna compare the cells to jobs in factory. give brainliest

job in the factory //       cell organelle   //  

shipping/receiving

department                 plasma membrane    

chief executive officer// nucleus

factory floor // cytoplasm

assembly line// endoplasmic reticulum

workers in the assembly line //ribosomes

finishing/packaging department //golgi apparatus

maintenance crew //lysosomes

support beams (walls, ceilings, floors) //cytoskeleton

power plant //mitochondria/chloroplasts

here's what each part of the cell does:

plasma membrane :

regulates what enters and leaves the cell; where cell makes contact with the external environment

nucleus :

controls all cell activity; determines what proteins will be made

cytoplasm :

contains the organelles; site of most cell activity

endoplasmic reticulum:

where ribosomes do their work

ribosomes :

build the proteins

golgi apparatus :

prepares proteins for use or export

lysosomes :

responsible for breaking down and absorbing materials taken in by the cell

cytoskeleton :

maintains cell shape

mitochondria/chloroplasts :

transforms one form of energy into another

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
