Answer:
C) Most coniferous trees have both male and female cones.
Explanation:
- Unlike flowering plants, conifers do not bear flowers. instead of flower they bear male and female cones.

- These pollen goes through a resting period and then fertilizes the ovule.that matures into seed.
- The seeds of conifers are naked. i.e. not enclosed

Answer:
Limited food supply and competition
Explanation:
Density dependent factors are those which in general lead to reduction of growth rate of population when the population density increases. One of such factor is availability of food and competition.
Whenever the density increased to an extent where the resources or available food becomes scarce or limited,then the growth rate of population decrease. These factors generally lead to logistic growth pattern of population.
