What is ecosystem ?All the organisms and the physical setting they interact with make up an ecosystem. The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue.
Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are biotic factors.
Healthy ecosystems maintain our soil, clean our air, control the climate, recycle nutrients, and give us food. They offer resources and raw materials for making medications and other things. They support our economies and are the cornerstone of all civilizations.
Thus, option B and C are correct.

n a strain of tomato plants, short plant height and small fruit size are traits that display autosomal recessive patterns of inheritance. To investigate whether the traits segregate independently, researchers cross a pure-breeding line of tall tomato plants that have large fruits with a pure-breeding line of short tomato plants that have small fruits. The researchers observe that all the plants in the F1 generation are tall and have large fruits. The researchers cross the F1 plants with one another to generate an F2 generation. The researchers record observations for the F2 generation and will use the data to perform a chi-square goodness-of-fit test for a model of independent assortment. The setup for the chi-square goodness-of-fit test is shown in Table 1.The researchers choose a significance level of p=0.05. Which of the following best completes the chi-square goodness-of-fit test?
For researchers who choose a significance level of p=0.05, the chi-square value, the critical value is mathematically given as
9.24, 7.82.What is chi-square goodness-of-fit test?Generally, The Chi-square goodness of fit test is simply defined as a hypothesis test that determines if a variable will originate from a certain distribution.
