I think it's A but I could be wrong so really sorry if I am
The correct answer is (d) The number of plants and birds increases and the number of snail decreases.
Green plants are eaten by snails, snails by birds, and birds by household cat. If cat is removed from the cycle then the number of birds will increase which will decrease the number of snail in the environment. As there are large number of birds there will be a great demand of snails as a food for birds. Then there will be a decrease in the number of snails because of over eating of snails. There will be an increase in the number of garden plants because very less number of snails are left that will eat garden plants.
The answer is; YES they do
Photosynthesis is important in taking carbon from the atmosphere . This is why forest are great carbon sinks because they sequester carbon from the atmosphere. Cellular respiration, on the other hand, is the opposite of photosynthesis. It increases the levels of carbon in the atmosphere by breaking down carbon-based foods to carbon dioxide.
The tertiary consumer will receive 500 calories.
<u>Explanation:</u>
Calories produced by the producer = 500,000
The flow of energy through different trophic levels is 10%
After producer comes the primary consumer followed by secondary consumer followed by tertiary consumer.
Energy reached to primary consumer = 
= 50000 calories
Energy reached to secondary consumer = 
= 5000 calories
Energy reached to tertiary consumer = 
= 500 calories
Therefore, the tertiary consumer will receive 500 calories.
<span>substrate-level; oxidative
Glycolysis will produce 2 ATP, 2 NADH, and 2 pyruvate molecules. If the body has oxygen, it could continue to do </span>oxidative phosphorylation in the tricarboxylic acid(TCA) cycle which will give much more energy(total 38 ATP) than substrate level phosphorylation.
