Answer:
Autotrophs are organisms that use light energy or energy stored in chemical compounds to make their own food.
1st order heterotrophs are organisms that eat only plants
2nd order heterotrophs are organisms that eat herbivores
3rd order heterotrophs: organisms that eat herbivores and other carnivores
Top group: carnivores
Explanation:
Producers are named as such because they produce their own food either by photosynthesis or chemosynthesis. These organisms are called autotrophs and include plants.
There are various levels of consumers. The first is first order heterotrophs, which feed on the producers. These are herbivores and include, for example, a deer feeding on grass.
The next is second order heterotrophs, which feed on the first order heterotrophs. E.g. an owl eating a mouse. These are carnivores
The next layer are also carnivores, third order heterotrophs which eat second order heterotrophs, for example a lion eating a zebra.
Answer: Hydrophobic hormones
Explanation:
Hydrophobic hormones are able to diffuse through the membrane and interact with the intracellular receptor.
These hormones travels in the blood plasma which is bound to the plasma protein.
Example: Steroidal hormones are highly hydrophobic in nature.Steroids are sex hormones related to the maturity of the body.
Answer: Option B
The enzyme has changed shape because of high temperature.
Explanation:
Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.
High temperature changes the shape of enzymes.
Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.
The environmental parameters that should be monitored to ensure that the plant is not adversely affecting the animal species near the plant are MIGRATING BIRD POPULATION AND THE CARRY CAPACITIES OF THE LOCAL ANIMAL SPECIES. Monitoring these parameters, we allows the city to know if the plant set up is affecting the population of the animals in the area.
