Answer: The correct answer is 1%.
In a food chain, only 1% to 2 % of the total available solar energy is transferred to the producers. The rest 98% to 99% of the solar energy is reflected by the leaves and other surfaces on earth, which is then absorbed by some other materials that convert it into heat.
Thus, 1% solar energy is available to the producers in order to synthesize their food in the process called photosynthesis.
Answer:
The correct answer would be c. pupil.
Pupil refers to the adjustable opening present at the center of the iris.
It appears as a black hole present at the center of the eye through which light is passed into the eye.
The iris is muscular and contractile structure present around the pupil.
The pupil regulates or controls the amount of light entering the eye with the help of iris.
Iris through its contractile nature regulates the size of the pupil and thus, it controls the amount the light passing through the eye.
The adjustable opening in the center of the eye controlling light entry is the pupil, with size adjustments regulated by the iris.
The adjustable opening in the center of the eye that helps control the amount of light entering the eye is called the pupil. This integral part of the eye widens or narrows to allow more or less light to enter, respectively. The pupil's size is regulated by the surrounding muscle structure, the iris, which adjusts depending on the intensity of light present. Unlike the cornea and fovea, which have different roles, the pupil specifically controls light entrance.

B. cities
C. forests
D. industrial areas
Hedgerows have created new ecosystem within Britain's farms which are patchwork quilts.
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By the decomposition of the dead plants and animals by action of microbes nutrients are released back in to the soil.

Answer:D. Heart and lung function
Explanation:the word “cardio” relates to the heart
Cardiorespiratory fitness refers to how efficiently the heart and lungs work together to deliver oxygenated blood to the muscles during exercise. It's essential for cardiovascular health, quality of life, and longevity.
Cardiorespiratory fitness refers to the ability of the heart and lungs (option d) to supply oxygen-rich blood to the working muscle tissues and the capacity of the muscles to use oxygen to produce energy for movement. This involves the circulatory and respiratory systems' abilities to transport oxygen throughout the body efficiently, maintaining overall health and stamina.
An individual with high cardiorespiratory fitness can sustain large-muscle, dynamic, moderate-to-high intensity exercise, such as walking, running, bicycling, and swimming, for prolonged periods. This capacity is critical for preventing cardiovascular diseases, improving quality of life, and promoting longevity.
