To make an argument about how environmental imbalance affects the ecosystem of the Chesapeake Bay, research on reliable sources on the topic is necessary.
How is the Chesapeake Bay?The bay corresponds to the largest ecosystem of estuaries in the USA, being a source of diverse types of habitat for wildlife, with more than 3,600 species of animals and plants.
An example of the environmental imbalance in the area is the commercial and recreational fishing of blue crab, whose population had a significant reduction in 2022.
Therefore, environmental factors and human exploration are responsible for generating such an imbalance, and the development of policies and actions to promote sustainability is essential.

Why are producers so important
to ecosystems?
A. Producers are used to put water into the air of
dry places.
B. Producers help transfer energy from
secondary to tertiary consumers.
C. Producers capture energy and convert it for all
organisms to use.
Answer:
C
Explanation:
Producers are also known as autotrophs, which they make their own food. Producers capture sunlight energy and use it to convert CO2 (carbon dioxide) and H2O (water) into O2 (oxygen) and C6H12O6 (glucose) for other organisms to use. This process is called photosynthesis.
this is a simple diagram of a food chain:
producers --> herbivores --> carnivores --> top carnivores
if all the carnivores die out, why does the number of producers decrease?
i'm not sure but what im thinking is, well if carnivores die, then not many herbivores will die, therefore there isn't that natural soil fertilizer due to the dead bodies.
Explanation:
By all the carnivores, I assume it means regular and top carnivores. This will let the herbivores live longer which means they eat more food, food being producers causing producer numbers to fall drastically
How does water enter a plant?
A) through the stomata
B) through the roots
C) by active transport in root hair cells
D) by osmosis in root hair cells
Answer:
Explanation:Most of the water that a plant takes in enters through the root hairs. The water diffuses easily (and osmotically) into the root hairs because the concentration of dissolved materials in the plant's cellular cytoplasm is high.
Describe and account for the relationship between the two population growth curves between hares and lynx.
Answer:
The lynx's principal food source is the snowshoe hare. These two species' population cycles are intertwined. When hares are abundant, lynx consume almost nothing else and kill two hares every three days. When hares are sparse, lynx eat mice, voles, squirrels, grouse, ptarmigan, and carrion.
1. Explain why testosterone can improve performance in sport.
2. Describe the role of oestrogen in the menstrual cycle.
Answer:
1How does testosterone enhance performance? Testosterone acts on muscle cells by binding to a specific receptor protein, the androgen receptor. Upon testosterone binding, the androgen receptor signals to the muscle cell to activate the pathways that trigger an increase in muscle mass, called muscle hypertrophy.
2The oestrogen causes growth and repair of the lining of the uterus wall. Oestrogen inhibits FSH. When oestrogen rises to a high enough level it causes a surge in LH from the pituitary which causes ovulation where an egg is released from the follicle (Day 14 of the cycle).

When a hypothesis has been tested several times using experiments and found to be true, such a hypothesis becomes a theory.
What is a theory?A theory is a hypothesis that has been tested by experiments by several independent researchers.
Hypotheses are tentative statements without any scientific proof or backing. They can be tested using experiments.
Hypotheses remain accepted when there are supportive experimental data and become theories when several independent experiments support them.

Charles Darwin’s findings were pivotal to the formation of the theory of evolution. He noted that the Galapagos Islands, which are located about 1,000 kilometers away from South America, were made up of different types of finches. These species were all believed to have evolved from a species on the mainland, but they developed different adaptations to survive in their environment. Based on this information and the image, answer the following questions.
Answer:
What is the Galapagos Islands in Ecuador the site of Darwin's note on?
Darwin first came to the Galápagos in 1835, on a ship called the HMS Beagle. His observations of wildlife on the island inspired his theory of evolution by natural selection
