Part B Now conduct research on the types of organisms that live in the ecosystem you chose. Note that
quaternary consumers and even tertiary consumers can include land animals that rely on the animals in
the aquatic ecosystem for food. Collect information based on these guidelines:
. Producers: Identify 2-3 species.
Primary (or first-level) consumers: Identify 2-3 species.
. Secondary (or second-level) consumers: Identify 2-3 species.
Tertiary (or third-level) consumers: Identify 2-3 species.
• Quaternary (or fourth-level) consumers: Identify 1-2 species.
Write down the species you've identified for each consumer level in the ecosystem.

Nteractions between organisms and their environment impact the organism’s overall population. oahu amakihi and kauai amakihi are two closely related species of hawaiian honeycreepers. they have a common ancestor, eat small insects and nectar, and like to nest in koa trees. however, one species is found on the island of oahu, and the other is found on the island of kauai. which concept shows the relationship between oahu amakihi and kauai amakihi?

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i.e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.

Will mark branliest. the theory of plate tectonics was developed with the contribution of scientists from many different disciplines. which of the following is a contribution from geophysicists?
