Answer: An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.

There are choices for this question namely:
<span>1 Lifelong passive immunity
2 Long lasting active protection
3 Immediate passive short term immunity
4 Stimulation for the production of antibodies
</span>
The correct answer is "immediate passive short term immunity". The administration of tetanus immunoglobulin will directly attack toxins associated with tetanus for a short time, providing short term immunity and this effect is immediate.The passive immunity from tetanus immunoglobulin is not lifelong. Choices 2 and 4 talks about active immunity which is not characteristic of tetanus immunoglobulin injection.
Photosynthesis, how plants survive. Sunlight is absorbed.
Fish and bird are biotic and the bird would hurt the fish depending on the species of birds since some birds are carnivores.
