which of the following is true about tertiary consumers compared to primary producers in a sunlight dependent ecosystem?
Yakvenalex [24]

Tertiary consumers produces less biomass but result in higher biomagnification.

<h3>What are different types of consumers?</h3>

Compared to primary consumers, tertiary consumers spend less energy. Organisms that eat secondary consumers are considered as tertiary consumers. Primary consumers are herbivores that devour plants. Consider insects. Secondary consumers are small carnivores that eat other animals, often herbivores. Consider frogs. Tertiary consumers are large carnivores that eat other animals, particularly secondary consumers. Consider birds. Bugs, frogs, and birds(First-tier consumers) The secondary market (Tertiary consumers).

The higher an animal is on the food chain (such as third-party consumers like seals), the higher the concentration of DDT in their bodies as a result of a process called biomagnification.

1. The best answer is Stomata takes in carbon dioxide and release oxygen. Photosynthesis is the process that take place in the leafs of green plants where chlorophyll absorbs sunlight and converts the energy from the sunlight to chemical energy. The process produces simple sugars and oxygen, oxygen is either released to the atmosphere or used in cellular respiration. Simple sugars (glucose) are stored as glycogen and used as an energy reserve. 

2. The statement is true. Water and carbon dioxide are are raw materials of photosynthesis. Water is broken down in the first stage of photosynthesis using sunlight to produce oxygen and hydrogen ions. The second stage of photosynthesis involves carbon dioxide fixation producing simple sugars 
(glucose).

3. The equation that supports the conservation of energy is;
 6CO2 + 6H2O + light = C6H12O6 + 6O2
This is the process of photosynthesis that involves use of carbon dioxide and water to produce glucose and oxygen. 
Six carbon atoms are used to generate another six carbons in glucose, hydrogen atoms and oxygen atoms taken in remain the same in the products.

What is the role of decomposers in an ecosystem?​
Misha Larkins [42]

Answer:

Decomposers are responsible for breaking down dead animals bodies into waste, more commonly known as food for themselves, and a more clean ecosystem. You can thank decomposers such as mushrooms and fungi for making sure the ecosystem does not consist of dead bodies.
