Q. No.MacArthur's Warblers could coexist due to
1. Behavioral differences in their foraging activities
2. Temporal differences in their foraging activities
3. Spatial differences in their foraging activities
4. Both 1 and 3
The occurrence of competition in nature, proof for this, comes from
1. Resource Partitioning
2. Co-existance
3. Competitive release
4. Behavioral changes in foraging patterns of warblers

1. Co-evolve
2. Competition
3. Predation
4. Mutualism
Parasites often have one or two intermediate hosts or vectors

2. To facilitate parasitization of its primary host
3. To cause advanced life cycle
4. To infect a broad range of organisms
The human liver fluke
1. A trematode parasite
2. Depends on two intermediate hosts- snail and Dog
3. Both 1 and 2
4. Simple life cycle
Which of the following is not correct with respect to parasites?
1. Harm the host
2. Reduce survival, growth of the host.
3. Doesn't affect population density of host as no effect on reproduction ability of the host
4. Render host more vulnerable to predation by making it physically weak.
