Explanation:
The hummingbird's nutritional needs daily are 10,000 mg of sugar and 8,000 mg of protein.
Since one nasturtium flower provides 10 mg of sugar and 10 mg of protein, the hummingbird needs 1000 nasturtium flowers each day for its nutritional needs (10,000/10 = 1000).
Since one honeysuckle flower provides 20 mg of sugar and 10 mg of protein, the hummingbird needs 500 honeysuckle flowers each day for its nutritional needs.
If the hummingbird feeds only on nasturtium flowers, then the bird will need 5,000 seconds to get exactly the food it needs. This is calculated based on the information that it takes 5 seconds to feed on a nasturtium: 1000 flowers daily * 5 seconds = 5000 sec = 83,3 min.
If the hummingbird feeds only on honeysuckle flowers, then the bird will need: 500 flowers * 20 seconds = 10,000 sec = 166,6 min.
