Answers

Answer:

1.a. Omnivores, Carnivores, and Herbivores.

1.b. Foxes, Tigers, and Deer.

2.a. A photosynthetic organism (such as a green plant or a cyanobacterium) that utilizes energy from light to synthesize organic molecules Green plants that convert carbon dioxide into carbohydrates in the presence of sunlight are called photoautotrophs.

2.b. Maize Plant.

3. Chemoautotrophs made their food by themselves using the energy from the sun. This means that an ecosystem that depends on chemoautotrophs for food is dependent on sunlight for food and survival because chemoautotrophic organisms are the primary producers in that ecosystem.

4. Decomposers are organisms that break down dead plants or animals into the substances that plants need for growth.

5.a. They keep an ecosystem free of the bodies of dead animals, or carrion. Scavengers break down this organic material and recycle it into the ecosystem as nutrients.

hummingbirds have small, weak feet and rely on their strong wings to move from one place to another. Describe how a disease affecting the muscular system would affect the other body systems of the hummingbird.

Answers

The muscular system of an organism controls the organism’s muscles. When a hummingbird’s muscular system is affected, the muscles will become weak from a disease and they will potentially die because they will not be able to survive without the strong support of their legs or any other muscle in its body.
We know that humming birds are animals that strongly rely one their wings to move around because of their extremely week legs.A disease targeting the muscles of a humming bird would be lethal to the bird.This is because muscles work in pairs to move parts of a body and if a humming bird has a disease effecting it's muscles it would prevent it from flying and do reasonable damage to the movement of it's legs and since humming birds have week legs they would not be able to survive in the wilderness and will suffer for time before dying of starvation,thirst, or an attack....

A place of the charts,

A place where happiness flourishes and blooms,

A place where many good memories live,

A place where a child takes his first steps,

And a place where he takes his last,

A place to be given on and on,

And the sound of water is never forgotten,

A place where blue skies are kept,

Where cold drinks and sunshine are common,

A place to connect with friends and family,

The docks.
