Greater light intensity would mean a faster rate of photosynthesis in plants. photosynthesis takes in carbon dioxide and water to produce glucose and oxygen. therefore, a greater light intensity would mean faster oxygen production
<span>This is avoidance conditioning. Brenda has been able to successfully link the over-the-counter heartburn medicine to an avoidance of discomfort. By taking the pill, she has received a negative reinforcement due to the removal of the indigestion. The reinforcement will likely lead to Brenda continuing to take the medicine until she habituates to it and does not receive the same benefit(s).</span>
The correct answer is: a. the agar and air in the petri dish are providing all of the resources needed by the bacteria.
There are four phases of bacterial growth:
1. Lag phase-bacteria prepare for reproduction
2. Log phase- cell doubling
3. Stationary phase- due to a growth-limiting factor
4. Death phase.
So given the suggested food chain of algae-snail-sunfish-heron we can conclude that this food chain is heavily dependent on the process of photosynthesis.
The algae is the only of the organism that are directly dependent of the photosynthesis for their survival, while the snail, sunfish, and heron, and indirectly dependent on it.
Since we are talking about a food chain, in essence it means that all organism are connected through one another. So the algae perform photosynthesis for its own survival, the snail is using the algae is a food source, the snail is later eaten by the sunfish, and the sunfish goes on the menu of the heron.
If the algae, by some scenario, are not able to perform photosynthesis, than they will die off, and if they die off, than the snail will die off because of lack of food, if the snail dies off, along with it dies off the sunfish because of lack of food, and if the sunfish is out of the scene, the heron goes as well.
So we can conclude that the process of photosynthesis is of crucial importance for the survival of all four species, be it directly or indirectly.
