It could perhaps provide a better understanding of why dinosaurs went extinct. It could also provide some of the things Dino's ate and their average life style.

Plz help oh and one of the questions is what percent of energy does an individual get from the individual it eats
liraira [26]

1. An example of secondary consumer is snake. Secondary consumers are the ones who eat the primary consumers, which makes them carnivore.

2. Photosynthesis is a process used by plants and (some other organisms) that converts water (H2O) and carbon dioxide (CO2) with the presence of sun energy (collected in the chloroplasts) into chemical energy that is later stored in sugars (carbohydrates). Organisms that do the photosynthesis are called autotrophs (produce food by themselves).

3. The energy pyramid represents energy flow in a community, where the different levels represent different groups of organisms.  

The food chain is a circulation of energy that comes from the sun and passes from the producer organisms to the primary consumer, secondary and tertiary consumer organisms.  

4. For example, plant is producer that is eaten by primary consumer-herbivore (e.g. bugs). Than secondary consumer-carnivore (e.g. snake) eat that herbivore and than is being eaten by tertiary consumer (apex predator that have no natural predator).  

5. One trophic level gets only 10% of the energy of the previous level. So, if the plant have 10.000 units of energy and is eaten by rabbit, rabbit gets 1000 units of energy, and when the fox eats an rabbit, it gets 100 units of energy.  

6. Trophic level is the position of an organism in the food chain.

Choose the true statement(s) about mutations. To be marked correct, you'll need to select all true statements, as there may be m
Kazeer [188]

Answer

All four options ( A,B,C,D ) are true about mutations.

Explanation:

A-  <u>Mutation can provide an evolutionary benefits</u>

As mutation helps in creating DNA  sequence ,new allele(variant of gene) for a specific gene , thus mutations is known to be the first step of evolution.

B-<u> Mutation leads to genetic and phenotypic variation within the species. </u>

In mutation, genetic  variation (difference between individual/population) takes place as new alleles are created ,random matings ,fertilization and during meiosis , recombination of homologous chromosomes. One of the type of mutation called gene mutation give rise to genetic variations.

Its an exceptional case of phenotypic variations ,as mostly there is no effect of mutation on phenotypic variation. Very few mutations lead to phenotype variation and in case mutation takes place in phenotype variation ,making the organism well suited to the environment, the a rapid change  in the characterstics of the individual species is seen.

C- <u>In humans, the somatic cell mutation are not passed in offsprings. </u>

Somatic cells are present in all over the body except in the cells that give rise to gametes( ie. egg and sperm cells) and produces offsprings . Thus somatic cells are absent in gametic cells ,therefore mutation cannot be passed to human's offsprings or children.

D- <u>Evolution rates are faster in bacteria than in humans because most mutations in human cells are silent.  </u>

Due to their fast  growth ,bacteria evolve quickly and share genes with each other and even between the species ,also the mutation that are helpful spread faster in bacteria.  

In humans, the silent mutation in human cells cause many genetic disorders like Laron dwarfism.  About 99.8% genes are silent mutation.
