An ecosystem is a structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interactions between organisms and their environment.
Answer:
An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue.
Parts & Functions Of an Ecosystem
The functions of the ecosystem are as follows: It regulates the essential ecological processes, supports life systems and renders stability. It is also responsible for the cycling of nutrients between biotic and abiotic components. It maintains a balance among the various trophic levels in the ecosystem.
What are the major parts of an ecosystem? An ecosystem includes soil, atmosphere, heat and light from the sun, water and living organisms.
Challenges For An Ecosystem
Some of the primary challenges include, but are not limited to, habitat loss, climate change including sea level rise, and levee stability.
The Role and Function of Water
Water cycle have several impacts on the nature - it takes part in weather, erosion and watering plants.
In short term it is positive, to see green grass and trees, not just bonedry dead nature.
In longer term we can see weather changing, clouds made of tiny drops of water coming and leaving - changing humidity (important for fungi and liches), local temperature changes etc.
Longest takes erosion and it is mostly about changing soils structure and nutritients for plants. Erosion can be also seen on riverbeds - in soft rocks/soils being wider, in harder rocks narrow. Also sedimentation in delta is important for development of border ecosystems.
Water makes organisms live and rocks move, that is the importance of water cycle.
Have a wonderful day! :-)

Explanation:
what is the difference between fraternal twins and identical twins in terms of gene reproduction?
Answer:
Fraternal twins are dizygotic and Identical twins are monozygotic.
Explanation:
Fraternal twins are dizygotic, meaning that they developed from two different eggs fertilized by two different sperms. Their genetic code is as similar (or dissimilar) as any other siblings. Identical twins are monozygotic, meaning that they developed from the same fertilized egg, and so have nearly identical genetic code.
__________ is the water and dissolved substances that are not taken up by the cells and remain between the cells.
a) Lymph
b) Plasma
c) Hemoglobin
d) Thymus gland
Answer:
a) Lymph
Explanation:
Lymph is the water and dissolved substances that are not taken up by the cells and remain between the cells. It is a clear, straw-colored fluid that is found in the lymphatic system, which is a network of vessels and nodes that helps to circulate immune cells and defend the body against infection and disease.
Plasma is the fluid component of the blood that contains proteins, hormones, and other substances. It is a yellowish fluid that makes up about 55% of the total volume of the blood.
Hemoglobin is a protein found in the red blood cells that carries oxygen from the lungs to the tissues of the body. It is responsible for the red color of the blood.
The thymus gland is a small, triangular-shaped gland located in the upper chest. It is an important part of the immune system and plays a role in the development and maturation of T-lymphocytes (T cells).
Answer: lymph is the water and dissolved substances that are not taken up by the cells and remain between the cells.

The picture shows a Single-celled organism that has a nucleus and organelles, lacks a cell wall, and obtains food by eating other organisms. The organism also has cilia that it uses to move through water. Which kingdom should this organism be classified?
Science
Protista
Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won't be. They are small, although many are big enough to be recognized in a dissecting microscope or even with a magnifying glass. Nutrients are acquired by photosynthesis, ingestion of other organisms, or both.
Why are Chromosomes arranged in pairs?
A. One chromosome is from the mother, and the other is from the father.
B. DNA is a double helix.
C. The chromosomes are split more easily.
D. Genes can be dominant or recessive
Answer: B
Explanation: because the dna are a double helix and do have a chance to split a little more and let me know if you passed
How are antibiotics different from vaccines?
Answer:
Both vaccines and antibiotics provide strong protection against germs that cause infections. Vaccines strengthen your immune system so infections can't get started, whereas antibiotics help fight an infection that is already making you sick.
