A state agency wants to release endangered hawks but needs to determine the best site for their release. The state would like to know how many rabbits are in each area to determine which area has the largest prey population. Create a plan to determine how many rabbits are in each area to determine which site is the best location. Your plan should include specific information on how many animals will be tagged and how many samples should be taken to get the most accurate results. Use your simulation data to help you develop this plan

Answers

We choose that site which have large number of rabbits because rabbits are the food of hawks.

Which location should be selected?

That site should be considered the best which has large number of rabbits because rabbits provide food for hawks so increase in population occurs in that location. We know that rabbits are the food of hawks so without suitable amount of food, the population of hawks is unable to increase.

So we can conclude that we choose that site which have large number of rabbits.

⚠ANSWER⚠

Preformed vitamin A is found in foods from animal sources, including dairy products, eggs, fish, and organ meats. Provitamin A carotenoids are plant pigments that the body converts into vitamin A in the intestine

You can also get vitamin A by including good sources of beta-carotene in your diet, as the body can convert this into retinol. The main food sources of beta-carotene are: yellow, red and green (leafy) vegetables, such as spinach, carrots, sweet potatoes and red peppers. yellow fruit, such as mango, papaya and apricots.

Preformed vitamin A is found in animal products such as meat, fish, poultry, and dairy foods. Precursors to vitamin A, also known as provitamin A, are found in plant-based foods such as fruits and vegetables. The most common type of pro-vitamin A is beta-carotene.

Vitamin B12 is found only in foods of animal origin, therefore, vegans (strict vegetarians who consume no animal products) may need to supplement their diets with this vitamin.
