Bacteria and fungi have a similar role in the ecosystem. they both grow directly on their nutrient source and are heterotrophic, meaning that they ingest food to obtain energy. which of the explanations best describes the relationship between bacteria and fungi?
a) since they are both common pathogens, bacteria and fungi compete to infect the same host at the same time.
b) fungi and bacteria will always form a mutualistic relationship which benefits both species at the same time.
c) all bacteria are photosynthetic and all fungi are heterotrophic, so there is extremely little interaction between fungi and bacteria.
d) since bacteria and fungi are both decomposers, fungi secrete antimicrobial antibiotics, which decreases the competition from the bacteria against the fungi.

Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring? o a. populations will go extinct since the warblers will stop migrating to breeding grounds. b. populations will be unaffected since most species can quickly adapt to effects of climate change. c. populations will increase since warmer temperatures are generally beneficial to survival, d. populations will decline since individuals will be less likely to successfully reproduce, reset next
