How does a decrease/decline in a top predator impact biodiversity in an ecosystem?(GIVING HIGH AMOUNT OF POINTS FOR AN ANSWER)

Answer:

The ecosystem will fall out of balance.

Explanation:

The ecosystem will fall out of balance because once you remove the top predator, the plant-eaters will grow in numbers, they will eat all of the vegetation, and will either need to adapt or die. Predators are very important, as is everything in the food chain

Organisms that live in the savanna and grassland biomes have developed unique adaptations that aid in their survival. Which of the following adaptations would befound in a savanna plant, but not necessaily in a grassland plant?a. long roots
b. thick bark
c. water storage
d. bitter taste

Answers

Answer: c. water storage.

Savanna is a biome characterized by dry climatic conditions. This biome receives low rainfall as compared to grassland. Therefore, plants are adapted to prevent water loss. They have small sized leaves which prevent water loss by transpiration. Also, they have large tree trunk to store water thus help them to survive in drought conditions.

Chromosomes, which contain DNA, have several functions. All BUT ONE of these statements is a function of chromosomes. A) Chromosomes determine the traits of an organism. B) Chromosomes provide instructions to make proteins. C) Chromosomes determine the gender of an individual. D) Chromosomes help an organism produce usable energy

Answers

Answer: The correct option is D) Chromosomes help an organism produce usable energy.  

Chromosomes are the thread like structures made from the packaging of the nucleic acid DNA. They are localized in the nucleus of most living organisms.

Chromosomes do not help an organism to produce usable energy.

Rather they provide instructions to make proteins in the form of genes ( segment of DNA providing information for protein). Proteins are therefore used in determining traits of an organism. Chromosomes are also used in determining gender of an individual. For instance, the presence of Y chromosome determine the male sex and XX determines the female sex amongst human.

Thus, option D) is not the right function of chromosomes.
The correct answer is 

D) Chromosomes help an organism produce usable energy


Chromosomes do not, in any way, help and organism produce usable energy.
