Answer:
The correct answer is : Biosphere 2 is a model based on the creation of a miniature ecosystem with life support systems.
Explanation:
Biosphere 2 is a small model of the biosphere, which is planned by scientists and engineers, that is closed and isolated from the outside world. In this study or research, the strategy for modeling is utilized to show the performance and conduct or behavior of a real biosphere.
Researchers made a model or an artificial situation that can uphold living things. It has a scaled-down model of a tropical forest, a grassland, a sea with a coral reef, a desert, and a mangrove biosphere. In these conditions, a wide range of animal varieties was contained. Furthermore, a group of eight individuals additionally fixed themselves inside it.
Answer:
c and d.
Explanation:
a. the total amount of matter and energy increased.
b. the total amount of matter and energy remained the same.
c. matter and energy were lost each time they changed forms.
d. matter and energy were lost each time they changed locations,
As organisms feed within an ecosystem, energy flows from one trophic level to the other while matter is converted from one form to another.
However, less and less energy becomes available to support life as energy moves through the ecosystem from producers to consumers as a result of energy loss to the ecosystem. In addition, matters are also lost during conversion from one form to another.
Hence, matter and energy are lost each time they changed forms and locations.
Option c and d are correct.
Answer:
B
