Crowbrds lay their eggs in the nests of smaller birds. The fast-developing cowbird chicks hatch first, then push the other nest as they hatch. The cowbird classified as a

To determine the effect of intra-specific competition on the growth of saplings of Eucalyptus dives, an experiment was designed in which two set of pots were used. In the first set only 1 sapling was planted per pot. and in the other set 16 sapling were planted per pot. To check for the effect of intra- specific competition  of resources, a decreasing amount of water was added to each set, The results have been graphicallly indicated below. Which of the following conclusions can be best drawn from the study?

Two insect species were used in a laboratory experiment. For the treatment, both species were grown by themselves on a suitable food source. For the second treatment, the two species were grown together on the same type and amount of food as in the first treatment. The given figure show the result at the end of the experiment. Based on these results the two species should be classified as 

The figure below depicts life-history strategies for three plant species (a.b and c) along 3 axes: strength of competition with other organisms, level of disturbance in the habitat, and level of environment stress in the habitat. Species a grow in habitat where competition among species is high but disturbance and stress are low. Species b grows in habitats with high environmental stress but with low inter species competition.
