D) All the organisms in and around the lake, and the non-living components of the lake
Explanation:
An ecosystem comprises living and non living organisms that interact with each other through food dependencies, nutrient cycles, trophic levels and flow of energy, to form a system together as a community of biotic and abiotic factors.
An ecosystem is the association between the living and nonliving things in a location such as that of the ecosystem consisting of a the Sun, the weeds, and goat, that eats the weed, where the weed add absorbed sunlight to grow.
We first need to write the function in standard form.
y = -x^2 - 7x + 18
To find the axis of symmetry, we do -b/2a
The a and b are the coefficients of the x values.
So a would be -1 since -x is same as -1x
Follow that, b would be -7.
Then just plug the values in. - (-7)/2(-1) = -7/2
The axis of symmetry is -7/2
