The right answer is C. Level 1 (bottom).
Ecological pyramids occur in their basic producers (such as plants) and follow a sequence of several trophic levels (such as herbivores that eat plants, carnivores that eat herbivores, followed by carnivores that eat carnivores, And so on). The highest level is the top of the food chain leads to superpreders.
D) allele frequencies of some traits change in the population
Alleles can be phenotype (how they appear) and natural selection is when an organism changes in a way that helps them survive.
It can be the way their beaks are formed that gives them a better chance of catching food among other stuff (Darwin's investigation)
Or how they change their color to adapt to the sudden change in tree coloration (Pepper moths)
Answer:
The correct answer is explained below:
Explanation:
- Flooding and intrusion of salt water in the low lying areas can adversely affect human life. This can happen in the following ways:
- Flooding can cause many people to die due to drowning in the flood water.
- Many people lose their habitat and all their belongings due to the entry of water into the settlements having only the ground floors. These people need to rehabilitated to safer regions.
- The saline water percolates through the ground and mixes with the fresh water present in the water table, thereby making them saline and non-consumable.
- People have to face the dearth of food, drinking water, clothes and electricity until rescue operations are sent.
- Increased chance of transmission of water-communicable or water-borne diseases like diarrhoea.
The answer is D. All of the offspring would have one recessive allele, one dominant and purple flowers.
