Answer:
1. interactions
2. environment
3. sun
4. photosynthesis
5. chemical
6. producers
7. food
8. energy
9. organisms
10. herbivores
10. first
12. Heterotrophs
13. second
Explanation:
An ecosystem consists of a community of living organisms interacting with each other and the environment. The source of energy that fuels most ecosystems is the sun. Plants use the Sun’s energy to produce food in a process called photosynthesis.
Organisms that use energy from the Sun or energy stored in chemical compounds to produce their own nutrients are called autotrophs. They are also called producers because most other organisms depend on autotrophs for food and energy. Heterotrophic organisms that can’t make their own food may obtain nutrients by eating other organisms. A heterotroph that feeds only on plants is called an herbivore. Herbivores are also called first order heterotrophs. Heterotrophs that feed on other herbivores are second order heterotrophs.
1. What is the proper order of succession?
A. climax community- pioneer species-primary succession- secondary succession
B. pioneer species-primary succession-secondary succession-climax community
(I WILL MARK BRAINLEST )! or however you spell it !!
The answer fam is......... B. pioneer species-primary succession-secondary succession-climax community
"Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community"

Scientists find the same type of index fossil in two different locations on Earth. What can they conclude from this discovery?
A. The fossils are different ages due to the location.
B. The index fossils are the same geological age.
C. One index fossil is older than the other.
D. There is not enough information to make a conclusion.
2
Answer:
(B.) The index fossils are the same geological age.
Explanation:
When they are the same fossil, but in two different locations we know that they are both most likely the same age.
Complete the following statement
When the forearm is extended at the elbow joint, the ____________muscle acts as the agonist.
Answer:
triceps brachii
Explanation:
The triceps brachii is a muscle located at the arm. It is a posterior muscle consisting of a long, medial and lateral head which originates from the humerus. It also covers almost the entire length of the humerus.
The functions of triceps brachii are:
Extension of the forearm at the elbow joint. The extension and adduction of the arm at the shoulder joint as a result of its long head.Controls the movement of the elbowWhich of the following organisms is LEAST able to extend its geographical range in response to climate change? robins polar bears conifers butterflies
Answer:
The correct answer is: Polar bears
Explanation:
Mong the given four option polar bears are last able to extend their geographical range in order to deal with climate change as they are not able to survive on land with hot temperatures and prey found in these regions. They can not survive for longer periods of time without sea ice and cold temperature.
Sea ice helps in finding their food and without sea ice, it will also greatly affect, it is one of the reasons their population decreasing as the Arctic are rising and the sea is diminishing.
. How are mineral deposits formed around vents?
Answer:
When hot, metal-laden water spews from vents and mixes with the cold ocean, the metals precipitate. Large piles of sulfide accumulate on the seafloor and are eventually buried by sediments, modified by heat and pressure in the crust, and uplifted. Some are exposed on land when erosion removes the overlying rocks.
How is cellular respiration
connected to our muscular
system?
Answer:
Cellular respiration is a key role in returning the muscles to normal after exercise, converting the excess pyruvate into ATP and regenerating the stores of ATP, phosphocreatine, and glycogen in the muscle that are required for more rapid contractions.
