Cycads are gymnosperms that were diverse and abundant during the Mesozoic era. Extant species of cycads share many traits with those from the Mesozoic era. Cycads bear cones, are long-lived with slow growth rates, show late reproductive maturity, and have very few offspring. Based on this description, the cycads are

Answer:

Cycads belongs to gymnosperm

Explanation:

Cycads belongs to gymnosperm because they have naked seed and able to directly fertilized with the help of specific type of pollinator such as beetle. Cycads seeds are used for the treatment of diseases such as hypertension, musculoskeletal disorders, gastrointestinal distress, cough, and amenorrhea. Cycads are toxic to human health if ingested can cause death due to cycasin which is toxic.

Based on this description, the cycads are K-strategists with a Type I survivorship curve.

For better understanding, lets explain what the K-strategist means

  • survivorship curves is commonly known as a graph that shows the various ways or patterns of species survival as a function of age

  • K-selected species are simply known as species that has a low unique or intrinsic growth rate that leads or make the population to increase slowly until it reaches its carrying capacity.

  • Type I survivorship curve is simply refered to as a type of survivorship curve whose way or pattern of survival over time is where there is high survival chance throughout most of the life span. The individuals here often start to die in large numbers as they approach old age.

From the above, we can therefore say that the answer Based on this description, the cycads are K-strategists with a Type I survivorship curve, is correct
